I've been doing GM's as part of my leg workout for quite some time. I've never really gone heavy (~100 lbs tops), considering them to be more of a conditioning exercise than mass/strength-building.
So I read about how the powerlifters stack on the weight, and since my lower back and hams seem to be weaker points in my squats, I figured I'd step the GM's up a notch. On the first set I did heavier than normal (only 135 lbs), I noticed a little twinge in my left ham. It wasn't really pain, and it wasn't persistant, but it happens every time I bend forward for a GM now. It's like two muscle fibers are arranged one way when I'm standing, and they want to switch places when I bend forward, and then switch back as I erect myself.
Worse yet, now it happens even when I do them with lighter weight. It's not painful, really, just annoying, and a bit scary. I'm not sure if it's my body telling me to ease off, or just some wierd defect in my left hamstring?
Anyone got any advice? It doesn't happen with leg curls on a machine, btw, or with deadlifts or squats.
