I thought you were a big fan of the heavy lunges? Also you must remember that RJ doesn’t follow Charlie’s system, although I personally think it’s a much better program. I just think that there have been too many sprinters who have had success without squatting anything near maximal loads to say that it is totally superior to other options. Obviously it presents the best option for heavy loading and MU recruitment but oftentimes guys aren’t loading the bar enough to exploit these advantages. In this case I would argue that they would get more work and benefit from step-ups or lunge variations. I’m also curious to see what the effect of heavy OL’s (80%+) paired with something like the step-up is compared to similar loading on the squat.
