Where should you feel the strain for squats?
I've started to read SS and have been trying to improve my squatting technique by ensuring I use the hip drive. Today after the exercise the strain was in my lower back (where Rip says the hip drive should be coming from).
The other day my glutes were sore, which I read implies that I was not maintaining the correct angle between calves and hamstrings (i.e. the angle between calves and hamstring was too acute and my back too vertical).
The hip drive motion looks quite different to the way most people seem to squat!
My question is: should my hams feel sore (or does this indicate I'm doing a leg press), the glutes or the lower back.
