F*** yeah man.  I'm subbed to both his blogs(just fly and jumpscoach214).  His stuff is cool, especially the nervous system article and the single leg jumping ebook he put out.

Heck, everything is great, not just that.

I really like what he said with one-leg jumping, that "isometric-explosive" part. Nobody ever talks about that and I've said that first I think about 9 years ago, that the one-leg jump is more isometric in nature (keeping the leg rigid).

I've heard people say that sprinting is also isometric in nature, maybe due to short ground contact time. don't have links
"Performance during stretch-shortening cycle exercise is influenced by the visco-elastic properties of the muscle-tendon units. During stretching of an activated muscle, mechanical energy is absorbed in the tendon structures (tendon and aponeurosis) and this energy can subsequently be re-utilized if shortening of the muscle immediately follows the stretching. According to Biscotti (2000), 72% of the elastic energy restitution action comes from tendons, 28% - from contractile elements of muscles.

Why should I bookmark his site? Seems like a bunch of unnecessary over-analysis that will just derail someone's progress ala RJ, Yourself (Raptor), CCJ, etc.

Say NO to Maroko

And also NO to anyone who associates with him. No Taylor Allan. No Adam Scammenauger. No Kelly Baggett. No Elliot Hulse. No Jtrinsey. NO JUMP USA


Don't PM me asking me training questions. I'm here for the lulz. If you want help, post on the forums and get help from all the members, maybe even me.

Nah it's more of a technical analysis about one-leg jumping. Some people aren't aware of what they do wrong technically when they jump off one leg. Also, it's a good resource of true plyometrics and programming.

That's because it is, but once the top speed is achieved. That's why a top speed sprint is closer to the one leg jump while the acceleration part of a sprint is closer to the two footed jump (where voluntary concentric power is important).
