The McCurdy study is brought up now as exhibit “B” for evidence of muscle recruitment. If you read the study, the depth of the TLS (two leg squat) is only to parallel and they didn’t include glute maximus. The medial glute is important to linking the hip and foot but that’s why you do both single leg and double leg exercises. The quads are important muscles and often are looked at as simple pr

Would you mind elaborating a bit on hamstring EMG during cleans from the floor and hang? I’ve never seen any research on that. From what you wrote am I correct in saying you prefer hang cleans? Is this due to higher hamstring EMG from the hang?
Also not sure what you mean by premature foot roll. I would imagine that this would be shifting your weight from your heels to the ball of your foot early in the pull, however I would assume that was undesirable.

The olympic lifts from the floor are obviously different than the hang. The composite of all the training is the key here. My point the first pull (if done right) is very posterior chain dominant. The second (or hang) has hamstring contributions. The key is developing the total leg through training, not just one magic exercise.
A good program will use a handful of lifts per year with some single leg exercises done with various adjustments. Iike to clean from the floor for the PC development I see as I don’t do specific exercises unless a previous injury occurred.
Right now a few private studies done with real researchers are being paid by a syndicate of coaches……including you! I will give you the chart of all of the major muscle groups of the leg (sorry no sartorious!) and at what part of a lift what muscles are more “noisy” with an international lifter hitting loads that are realistic to athletics so no 2 x BW cleans that make it hard to extrapolate.
If you look at EMGs as a hint of what is going on and use basic physics you can see how a few exercises in a group can cover the bases if one things holistically. With all the youtubes of exercises people need to remember that we still have 24 hours in a day and so much energy a human can put out.
I will post more later…..

I once heard a wise man say that training the hang only = 4.2 low backs and 4.6 hamstrings.

What does this mean in lamans term? Single leg squat is the best?
Carl Valle on November 26, 2010 at 2:52 am #103561
What it means is that all exercises must be viewed in a complete program. It’s sort of saying we do acceleration work and this group does speed endurance. You should do it all but how much and when is key. I love single leg squats and exercises but I feel that moderate loads should be used. That’s just me.
