What are you views on wearing a belt during (training) squats and deadlifts? I used to wear it during my last 1-2 work sets. I now only wear a belt when I get to mid 400s. I found the belt was hampering my technique and causing me to emphasize my lower back during the movement. Since throwing the belt off, I am able to maintain a more vertical torso in both lifts and maintain proper mechanics. Thoughts?
