First of all, Sensei/Boris is the man. The Squat Rx series has some of the most informative vids I've seen anywhere.
Turns out I've been "GM'ing out the hole" for the past year now. I've already injured my lower back once doing that, and I don't want to repeat it. So my question is are there any routines you've developed to go with these exercises?
Specifically, I'm interested in trying:
one legged deadlifts
step back lunges
wide legged squats
I'm not sure the best place to add them to my split, how many sets/rep is best for each, or which shouldn't really be done on the same day.
Also, my hips aren't even flexible enough for me to squat as low as you are in these videos. How often do you recommend doing those power rack stretches, and butterfly stretches?
Last question. I'm going to replace back squats with front squats for a while, to prevent leaning forward all together. Since I'll be using less weight, should I try to do them twice a week, or load up on some of those other leg exercises above?
