Check out the dorsiflexion ^^^ he obtains vs your lack of dorsiflexion. If you manage to do this ^^ and land flat footed vs reaching out with your foot you're going to bound much better.
Also check the arm swing. He does double arm swings but I do it single arm... you need to go with whatever works for you.
You remind me a lot of myself when I first started doing bounds... I still do them like you do them here when I go LRLRLR but when I do them on the same leg, I can dorsiflex well. You don't dorsiflex at all in either version... that's the thing.
Ask Lance about them... post these videos there, see what he thinks. He knows more about bounding than I am.
Yeah I'm not "bothered" or anything like that... if I have a problem with what he writes, I can just ignore it and move on. It's great that he's passionate about it and wants to know everything, but at his current level he would be better served working his ass out and really focusing on the basics.
Sometimes the more you know the more that additional information can deter you off the right path, because you're anxious to "try something new, maybe this works better".
It probably happens because (at least I do) you tend to keep muscle isometrically contracted when you stretch... so... that's basically isometric strength training.
Damn, you really went down in that 3rd set ... 11+9 and then suddenly only 5. I have that tendency as well. Maybe we just have fast twitch fibers that don't have enough time to recover in 45 s
Would you do sprints before bounds (if you're to do them separately) or bounds before sprints? I personally do sprints before bounds because I get warmed up well after sprints.
