Title: One-leg wall sits
Post by: Raptor on January 06, 2011, 05:12:19 am
I was wondering if something like this with weights in hands could help single leg jumpers like me to help with quad strength:

http://www.youtube.com/watch?v=VE9KoQRCiDU

I used to do iso stuff for ~20s as a target (so adjusting my weight to be in the 10-20s range) on one leg with the BSS variety:

http://www.youtube.com/watch?v=zMEH2u0N-lY

What I'm doing seems more prone on the posterior chain thing but the wall sit on one leg seems aimed more towards the quad thing, and I need that. If I compound that with holding a plate in my arms at chest level or two plates to the sides at hip level, that might increase my quad strength. What do you think? Also, do you think I should focus on the 10-20s range (like RJ was telling some time ago) or go for a longer period of time?

 A while back you posted pics of your single leg plant vs other jumpers, I told you that you had a very knee dominant plant, this is the reason I think youre convinced your quads are the limiting factor in your jump, youre forcing more work on them than you need to.  The single leg wall sit is not a natural movment for the body, the hips are pinned and the torso is forced in a vertical position, a single leg squat iso to the same depth with a hand holding onto something beside you for balance is a better option imo.  The single leg standing glute bridge is a better option than both of them, you can focus on turning on the glute maximally in extension, strengthening the lower leg and getting as high on the big toe as possible, and stretches and strengthens the hip flexors simultaneously.  Working up to one minute while firing the glute, gastroc, and hip flexor maximally, the same way you will in a single leg jump, is a good starting place.  If you cant feel the glute firing on the iso, you damn sure arent going to be able to get to the glute in your jumps either.  Once you hit one minute on the iso you can easily hold dumbells by your sides.  In your case I think using something like this for a strength and activation movement would help you alot more and help you get to the glutes and posterior chain more in your jumps.

Yeah I know that, did it a couple of times.

If I'm to analyze my jumping mechanics off one leg by the way I feel my muscles activating (not by video), it really feels like the quads load a lot when I first touch the ground to go as breaks and stop forward momentum, they also push into the ground but then as I rise up and knee angle lessens I apply a lot of glute/hamstring power into the movement.

I always feel the quads as the limiting factor because they usually aren't able to break properly and the knee collapses. Probably because I bend forward sometimes in my plant as well.

I understand what you're saying, that I need to work on posterior chain activation so that the quad overloads less in the plant, but the quad still needs to stop the knee from collapsing and I'm not sure it has the amount of strength that I want it to have to prevent that, even with better posterior chain involvement. It's interesting when you think about  it though, that great glute activation can actually help against knee collapse through the illio-tibial band (the illio-tibial band acts as a knee extensor).

Strictly from a strength perspective, would the one-leg wall sit improve on that? (quad strength, especially VMO)?

 Exactly, the more hip dominant you make your plant, the less that quad is going to be a factor.

  Yes, that one leg wall sit will strengthen the quads to a certain degree but I wouldnt do it if I were you, youre going to be amplifying an already existing problem. Youre essentially putting the glutes at a disadvantaged position and forcing the load on the knee.  You could get really good at them and amplify your already knee dominant plant or you could teach your body to "get to the glute/hips" and have the quads not be as big of a factor as they currently are.  People who squat with the hips pushed in and knees coming a mile forward think the quads are the limiting factor in their squat too, they are, they can either strengthen them even more or change the way they squat.

 Ive worked with alot of excellent single leg jumpers throughout my career, the ONE thing ALL of the great ones had in common was insane hamstring strength (as a hip extensor), and great glute and posterior chain dominance in their movments.  Even the skinny ones had unbelievable strength and power in the posterior chain, the quad strength varied between different jumpers but it was never anything ridiculous compared to other athletes.  Even in bilateral landings, etc., things you would expect to be more quad dominant, they would load the posterior chain with very little coaching.

Post by: Raptor on January 06, 2011, 08:28:09 am
That's interesting. Let me tell you about my hams (sexy, I know) something equally interesting:

They really are strong, that's a fact. When I do my single leg leg curls, they are pretty much equal in terms of strength, speed of movement etc with the same weight. When I do hip extension stuff like straight leg one-leg deadlifts or lunges or step-ups, WEIRDLY I can do them much better on my right leg. That doesn't make any sense. The right leg is obviously weaker but if anything, it's really really weaker quad-wise and not posterior chain wise.

The left leg has much stronger and bigger quads (especially VMO) from the thousands of jumps I've done off it. And when I do lunges or step-ups, I feel so much better off the right leg because it probably hasn't been programmed to be quad dominant. Instead, if I jump off my right leg I bend at the knee like crazy and I'm 100% (or whatever) pure quad in that jump (~20 inch jump off right leg).

Really intersting. Glute dominant on strength exercises and quad dominant on jumps on my right leg. Interesting and weird. Any ideas on that?

It could also mean that one leg is hamstring dominant (in terms of posterior chain "separation") - the left leg, jumping one, and the other is glute dominant, the right, non-jumping leg. I'd rather have it in reverse and use more glute for the jumping leg if anything.

PS. This brings me to my discussions with adarqui with me telling him he should involve the posterior chain more and him replying that he doesn't thinks so, because the "quad is the way" for his structure. I don't really agree with him.

  The difference in quad strength you described is fitting , youre training the quads of your left leg extremely hard with all the unilateral quad dominant jumping.  The difference in the jumping right vs left can very well be a neural issue too, you likely dont practice jumping off of the right as much and even if you did, the posterior region of the right leg may not be as powerful as the quads have grown to be in your left leg in the jumping movement.  Alot of times when athletes learn to plant and jump differently, using the glutes and hams more off of one leg there will be an initial decrease in jumping height, the potential of the jump is much higher once this movement pattern is trained and solidified.  Another issue with typical strength exercises like squats, lunges, etc., is many people "overarch", they have an extreme curve in the low back, they are putting the hamstrings in a position to do more work than the glutes.  Both should be turned on but the glutes need to be loaded maximally in the single leg jump while the hamstrings assist the movement.

 Im very big on the standing glute iso hold shown, you can feel which muscle group is more active and many times it will be the hamstrings, you have to play with the pelvic position and learn to activate the lower abdominal region to really get to the glutes more.

 I like what youre currently doing in your program, once the low bar full squatting more than once per week levels off and youre not able to progress it linearly I would transition into one day per week of that squat and one day per week of a more spp movement like a single leg box squat, walking the working leg out a little in front of the body and working on getting the hips more active as well as speed-strength in the movement.  You can then progress both of them linearly for a long time, getting the best of both worlds.  

As far as the two legged jump and what youre telling andrew, its a different animal than the single leg jump by a long shot, if you were to relate the two to an upper body movement, think of the two leg jump as throwing a shot put with both hands like a bench press throw, and the single leg jump as throwing it like a baseball.  The role of the shoulder joint and chest (hips) is going to be different, and the role of the triceps (quads) is going to be even more different.  Different athletes with different structures, levers, strengths and weaknesses, etc, are going to use different muscles to different degrees in the two legged jumps just like they do in the bench press, some use much more tricep, some much more chest, etc.

Post by: Raptor on January 06, 2011, 04:44:26 pm
Yeah these are very smart things you say.

I actually did the glute iso hold today, 2 times per each side for about 20 seconds, but I haven't really paying attention to what muscle is dominant. I'd say it's a hamstring-lower part of the glute kind of thing for me. In fact, that's where I usually get sore when I do hip dominant activity.

You remembered me two other very illuminating things:

1) When I deadlifted the 1st EVER deadlift when I was 18 years old (and I can vividly remember that like it was... today :D) I used to lift the bar from the floor with 100% (or whatever) quad involvement. I used to just bend at the knees exclusively (knees going forward) with the hips TOTALLY de-activated (torse perpendicular to floor, upright) and I was feeling totally "natural" that way.

People were saying to me "that's not how you deadlift, you need to keep your back straight and use your hips" and I just couldn't even conceive what "using the hips" means at all. I wasn't even aware you can do that movement.

and

2) When I jumped at a basketball hoop for the first time ever (15 years old - and yes, I can remember this clearly as well) the jump was off one leg with the knee going out a LOT and all quad - jump was ~16 inches). Just over time, jumping and jumping and jumping at the rim the technique kind of started to change on it's own without any strength training or anything... I think the body just recognized a better movement pattern automatically and just sticked with that. Interesting.

I should film a right leg jump to see how ugly it is and how much quad dominant it is.

But anyway, I was thinking of dumbbell BSS or step-ups as SPP exercises with deadlifts as assistance or hip thrusts. Single leg box squat sounds good though - the more in front the foot, the more PC involvement so I can control that. Do you talk about pistol box squats variants or barbell box squat variants? (I assume barbell).

PS. This quad dominance I think it's keeping me from doing things like snatches and power cleans as well. The bar is in front of the body and I automatically feel the "need" to lean forward, load the knees (quads) and jump which wrecks everything.
Title: Re: One-leg wall sits
Post by: LanceSTS on January 06, 2011, 06:20:31 pm
  Thats very common to get more upper hamstring/glute tie in on the iso at first, it seems almost counter intuitive but you need to learn to push down into the glute with abdominals, while maintaining neutral with the spine, this usually fixes it once youve gotten to the point of feeling more upper ham (beginners usually fail at the quads before they even get to the hams, intermediates and some pretty decent athletes can usually get to the upper hams/tie ins, excellent athletes and elite jumpers usually get to the glutes without much cueing i.m.e.) The better you get at firing the glutes maximally, staying as high as you can on the big toe (try to lift the pinky side of the foot up if need be), the more powerful and used to this position the body will be, you will notice the body "wants" to get to full hip extension in your jumps, lifts, sprints, etc.  You will also notice how much stronger you are in that position once the glutes are dominating the movement.  

  What you were saying about your body naturally changing the jumping movement once you performed it more and more, this is also something very true.  Strength training can negatively influence this if the movement patterns in the weight room are favoring a more dominant pattern (making lowerbody movements quad dominant like squats, lunges, etc.) for an athlete needing a hip dominant movement in athletics.  The body will respond to the strength training (squatting like you were a while back, knees coming way forward, not sitting back into the hips,etc.) and gain strength in that movement pattern very quickly, affecting your jumping movement as well.  IMO, this is what causes the common issue of single leg jumpers who started strength training becoming double leg jumpers, no longer jumping well off one leg, they were training the body in a manner more fitting for a double leg jump.  Had they gone about this differently, choosing different movements, learning a hip dominant squat, etc., this would not have been the issue, they would improve both single leg and double leg jumps, but not LOSE their ability to jump well off one leg.  In that particular case, the single leg jumping athlete would have been better off not re training the movement pattern in the weight room, in favor of the more quad dominant movment pattern they attained from the exercises they used (usually a quad dominant squat,or other quad dominant exercises), if single leg jumping were their main goal.

  I like the single leg box squat much more than the other options, reverse lunges would be next on the list but you have the ability to walk the working leg out in front of the body more and more, allowing more of a "pull" and hip extension in the manner used in your event youre trying to improve.  I have never gotten anywhere close to the carryover with other single leg exercises as i have with the single leg box squat, coupled with the single leg cleans.  The hip dominant jump needed to be proficient in the single leg clean carries over very nicely to jump with the added benefit of the landing, youre killing alot of birds with one stone this way.  If youre having trouble getting your hips into your cleans and snatches, start with knees almost locked, push the shoulders as far out over the bar as possible.  The double knee bend will be forced to happen this way and you will get a ton more hip involvement in the lift.  Using the iso hold as an activation movement before the cleans and snatches will help also, the body will "want" to use the glutes more automatically.

Post by: Raptor on January 07, 2011, 04:55:23 am
Yeah probably squatting high bar or with partials is OK for one-leg jumpers as long as the volume of jumping is enough to maintain the form on the jumps (hip dominant) and not allow it to regress to a quad-dominant form because of weight training. There's still a big difference in movement and dynamics between jumping and strength work so only high volumes of quad-dominant strength work and low volumes of correct jumping probably can create that hip to quad dominant transition.

I assume you prefer a ROM that is specific to the jump ROM off one leg in terms of box height. Unfortunately, I don't have boxes in my gym (or any gym I can think of), I only have benches and if I'm to do them on the bench, that's ~ parallel depth.

Why do you favor the barbell variant vs. the pistol box squat variant with the weight held in hands in front of the body? I think one reason, if I'm to dig in, is that with the bar on the back there's even more weight on the back of the body so more glute/PC overload and another reason is that holding a weight in the arms in front of you can cause back problems.

Interestingly (and I need to film it) - I'm limited by shoulder strength with pistol box squats. I can hold a 25 kg plate at chest level and do a deep pistol box squat on my left leg, and it really feels extremely PC dominant (probably looks like that also, remember that pistol squat video of me) but I just can't hold that plate up there for more than a few seconds since my delts die after that so...

That's why maybe I should do both barbell single leg box squats in a workout and pistol box squats in another as a SPP thing.

PS. I need to film my cleans again... form is horrid.

  Yea, you see lots of high jumpers doing half squats which is fine, you can learn to recruit the glutes and hams in a half squat very well.  If the goal was primarily two leg jumping, I would use half squats ALOT, as an spp type squat as well.  The low bar position saves the knees of my jumpers, ESPECIALLY triple jumpers.  When they come in they have usually stalled or gone backwards in their jumps, have at least some degree of knee pain/issues, and have been using typical high jump/long jump strength training protocals for several years.  The long leg/short torso build that is the majority in this case, take alot of stress off the knees with the lowered bar position, and get much more hamstring activity with it as well, even with a fair degree of knee travel (note that im referring to shoulder width, bar across upper rear delts, knees tracking over feet, stance).

  Yes, if the strength training is NEW to the athlete, and the athlete is not a competitive jumper, or jumping extremely frequently, then the new stimulus of the strength training is going to weigh very heavily on their on court/field/track performance.  This is not nearly the same thing as an olympic high jumper, jumping and doing jumping drills/practice, five days a week, and doing 4 sets of 5 high bar half squats twice a week.  

The range of motion.... what has worked the best is starting at a larger range of motion, using the eccentric on one leg as well, and building a "base" first.  As the season nears the box height increases to a rom more specific to the jump, then transitioning into bands as well as free weight, with a two leg eccentric, explosive single leg concentric on one leg.  I can do them this way up to two days before the track meet and get pr;s in jumps.  The parallel depth wouldnt be bad at first, you will develop some great single leg strength that way and thats pretty close to the offseason box height I use.  I want them to be able to walk the leg out in front a decent ways, but also get a larger rom than they jump out of.  

 

Youre exactly right, I like the bar on shoulders since it loads the posterior region much more than the pistol version, you can move the working leg out in front of the body, and you can get very strong at this exercise, the weights held in hand would cause you to fail at the shoulders or hands before you adequately challenged the jumping musculature.  Putting the leg straight out in front of the body as in a pistol squat changes the dynamics of what im after as well, the non working leg will slightly trail the working leg in the slbs, finishing in front with the knee. (I have stacked plates under benches, etc. in commercial gym settings before with this exercise so thats one way around not having a box).

Yea, film the cleans, from the hang.  Earlier I may have not done a very thorough job explaining what I meant when I was explaining how to get more hip into the olympic lifts, start by standing straight up, legs almost locked, descend into an rdl position, again, knees should be almost locked.  Bar should be about mid thigh, shoulders as far in front of the bar as possible, then simply JUMP.  What will happen is the knees will bend when the bar slides up higher on the thigh, but the hips rather than the quads are leading the lift.   You sound like youre starting behind the bar, with knees already bent at the beginning of the hang position, this should fix that issue.

One more quick question:

In terms of VMO development, if I can't do half squats or 1/4 squats because of knee pain but I can do leg extensions, should I go with them? Just as an assistance exercise after my main workout things.

What about Peterson step-ups?
Title: Re: One-leg wall sits
Post by: LanceSTS on January 08, 2011, 09:54:43 pm
  I like the peterson step ups alot more, I dont think leg extensions are awful, I just dont use them with athletes.  One cue you dont see talked about often with step ups is to "pull" with the hams and glutes before you "push".  It will aid the knee stability, get the glute involved more, and transfer more weight onto the working leg.

 I worked with a bodybuilder a few years back that had problems with his vmo's, he had tried everything under the sun and they just wouldnt catch up with the rest of his leg development.  What worked was doing partials, at the bottom of the squat, he would go into a full squat, and "bounce" for 3 reps up to parallel and back down, then to a full standing position.  It was interesting as I tried different numbers with the partials at the bottom, 3 ended up being the most successful since the breath and tightness could be held for 3's, then he would return to a standing position after the 3rd and exhale, get another breath, and repeat.  In a typical set of 10 reps you get 30 reps at the bottom half this way, the vmo's responded insanely well with an added benefit of more glute development.   

  Just make really sure to include plenty of quad flexibility work as well, letting them tighten up on you is a good way to limit performance and have some more knee issues re appear.

I was under the impression that the VMO is activated in the last 25 degrees or so of extension, and I'm talking about the upper level of extension (so 1/4 to 1/8 squat). You say it's being activated at the bottom (full to parallel)? (wtf)
Title: Re: One-leg wall sits
Post by: LanceSTS on January 09, 2011, 06:44:28 am
  The vmo is recruited at the bottom of a full squat, theyre at an advantageous position to produce force in relation to other musculature at that point.  Charles poloquin has written alot about the same thing, using the bottom of a full squat to bring them up (and im not advocating everything charles poloquin says by any means) but apparently believes in them too for better vmo development.  here is an article where he talks about it briefly, he has alot more on them but im not gonna dig them up right now.

http://www.charlespoliquin.com/Blog/tabid/130/EntryId/154/Tip-1-C-Find-out-how-one-can-vary-a-few-minor-things-and-affect-percentage-of-muscle-contribution-in-the-squat-Part-3.aspx

If you think about the bottom of a full squat, the vmo is under a great stretch at that point, it also has to provide alot of knee stability at that point, so it makes perfect sense why it would be extremely active. 
Title: Re: One-leg wall sits
Post by: LanceSTS on January 09, 2011, 11:43:03 am
Here is a good clip from an article by John Furia on the subject:

"Three groups of 15 year old male and female athletes were put on a leg strength program consisting of just squats during the summer for 10 weeks.

Group One – Did Full Squats (full squat to floor)
Group Two – Did ½ Squats (squat to 90 degrees)
Group Three – Did No Squats. (No squats at all)

Results: The group that did the ½ squats was found to be the most often injured! In group one (the full squat group) no knee injuries over the next one year were reported. In group two (the ½ squat group) 3 of the five athletes reported some kind of knee pain or injury. One ACL tear in a female, patella tendonitis in a second female, and an MCL sprain in the third athlete a male! The other two reported no incidence. In group three (the no squat group) 2 of the five reported knee injuries, an ACL rupture in a female and quadriceps tendonitis in a male athlete the other three reported no incidence.

Conclusion: This research study is one of many that bear out the fact which is common knowledge in strength training research. Females are more susceptible to ACL injuries due to hormonal levels and quadriceps angle or Q-Angle (increased angle of the femurs). Doing half squats can cause flexibility deficits and muscle imbalances to the quadriceps. EMG (electromyography) studies show the ½ squat under recruits the VMO or Vastus Medialis oblique (the teardrop or inner portion of the knee), hamstrings and gluteals forcing the lateral quadriceps to do most of the work. Omitting squats completely will deprive the athlete of knee and hip stabilization that may help prevent or reduce knee injuries. Half squatting disallows the knee to travel across the toes and move through a full range of motion again facilitating quadriceps/muscle imbalance by under recruiting the VMO muscle which is the pillar of knee joint stability. "

There are studies both ways, and alot of it is going to depend on HOW you squat regardless of depth, but from my experience doing mini reps, from the bottom of the squat back up to parallel as i mentioned earlier, is extremely effective at bringing up a lagging vmo issue and has the added benefit of more glute work in the process.

Post by: Raptor on January 09, 2011, 12:03:34 pm
Well I can full squat only if I have a very wide stance... otherwise I feel like I''ll fall back on my butt, even with the heels elevated. That means I'm compensating with a lot of forward knee bend...

Do you know if the VMO is activated even with wide stance full squats?

And yeah, I did 1 & 1/2 squats before... never to three reps though.
Title: Re: One-leg wall sits
Post by: LanceSTS on January 09, 2011, 12:16:07 pm
  Your squat depth is deep enough as is, you dont need to try and go any deeper.  Just decend into the bottom, rebound about a foot up, then back into the bottom.  I usually do those in my warm up sets, I find that my work sets are much easier and in better form.  Its like a dynamic stretch + weak point improvement in one.
Title: Re: One-leg wall sits
Post by: Raptor on January 09, 2011, 03:32:07 pm
Yeah I agree, my only issue is the squat stance. It's really wide, I can't even squat narrower (even with the heels elevated it still feels like I'll fall on my back).

 Your stance is not "wide" at all, youre not a 5'3" olympic lifter, your stance is going to vary according to individual levers and hip structure, I think that stance in the video is perfect for you and I wouldnt change it if I were you.  If you want more depth try pushing out to the sides of your shoes just a little more, that will open the hips up and let you get a little deeper without making you feel like you will fall over backwards.

Well I look at how other people of my height are able to squat full and they definitely can squat narrower... I mean, look at adarqui. Although I haven't seen him squat full.

 Yea you gotta stop doing that man, youve finally achieved a good, usuable, technique in your squats that you can progress without injury, dont fix things that arent broken, especially over wanting it to look like someone elses squat.  That squat youre performing is a good example of an athletic style squat with an athletic style stance. btw, adarqs feet are about the exact same width as yours and he may have narrower hips than you as well.

I have my Olympic high jumper friend that's 6'4-6'5 and can squat narrow but always squats high bar with heels elevated... he has great flexibility but then again - he's been at the Olympics in 2004 I think. So I can't really compare myself to Olympic athletes (although I am comparing myself - you need to aim to the highest level if you're to improve). But he probably is so much more flexible.
Title: Re: One-leg wall sits
Post by: LanceSTS on January 10, 2011, 06:02:53 am
 Right, the width of the hips on alot of those guys is usually narrow, theyre structure is different and his squat stance isnt gonna be the determining factor in his high jump success anyhow.  Youre not super wide or super narrow, so anything in between is fine and where u feel most comfortable is going to mean alot more than copying someone elses stance.
Title: Re: One-leg wall sits
Post by: Raptor on January 10, 2011, 06:22:21 am
Yeah definitely. I think it's smarter to go with a narrower, more jump-related stance with half squats since you're going for specificity anyway.

Yea man, the position youre put in is not very conducive to using the glute/hams and puts alot of stress on the knees in an awkward position , there are alot of better options discussed earlier in this thread that you may want to try.  It is possible to learn to engage the glutes and posterior chain by isometrically performing a leg curling motion with the working leg, but alot of people will have a hard time doing this, especially with the single leg version, and end up with more knee pain than anything for their troubles.

Wordx1000 on this. I got my girl to put a little bit of resistance on the sole of my foot while I laid on my back and extended my foot (with the sole facing skyward) up. Basically the same thing with I think and it got my glutes working so much better.

I re-read this entire thread and it really opened my eyes on a lot of things. I need to try to get that 1 minute for the glute iso holds and see what happens. My calves usually start to cramp after 20s though - but I will definitely focus on trying to get to 1 minute while maintaining maximum glute contraction for the entire duration of the set.

I'll also give that 3-bounce full to parallel squat for VMO development thing a try.

Thanks again.
