I'm sure this has been asked but what do you think about using them while training? A guy I know at my gym never uses them unless he is doing a lot more than his training weight and/or is competing which is very infrequent for him. He feels they are a crutch. Currently, I use it for squats and DLs exclusively. Should I try to work it out and if so will it help strengthen other parts of my body, i.e. abs?
Lately, I've noticed me tightening the belt less and less because I'm teaching myself to keep my back arched even without it.
What do you think?
