I've read claims that lifting belts don't help that much. I have been having some lower back pain lately from heavy leg workouts. When I do squats it puts strain on my back and I am not going to stop doing squats. I was just wondering if anyone uses a belt while doing squats and if it is totally necessary. I am also planning on working hyperextensions and stiff legged deadlifts into my workout. I'm still ironing out a solid routine and trying to get everything into place. I'm just looking for other peoples views on lifting belts, pros and cons.
