i bet most of us were lifting with those in our garage at 12 years old.
Actually, I was lifting in my living room. Since the magazines talked about training to failure and I trained alone, I'd put 80 lb on the car and screw on the collars. Then, I'd put the extra cement weights outside the collars.
I'd bench to failure then dump the weight off, leaving just an 80-lb loaded barbell to press back to the uprights.
Of course, since I lived upstairs, the neighbors complained. Then, I simply took the cushions off my mom's couch and surrounded the bench with them.
