So I'm at the gym last Saturday doing my leg workout and because I only did a few sets of front squats instead of my traditional back squats, I thought I would do a few sets of leg press on machine at end of workout and call it a day.. So the first set I'm going steady pace but not real heavy and a twinge in my lower back at about rep 7.. I knew instant I strained something so I stopped immediately and of course when my muscles cooled down, it hurt like a b**ch. so I guess my question is has anybody tweaked back doing leg press (machine or otherwise)? Should I wear a belt for a bit even on leg press machine? I was going to start new program Saturday with legs but scared to hit the weights heavy? My back is still a little sore today and hoping by Saturday if I wear belt I can go a little harder??? Anybody have advise or back pain story from leg press?
