@riosvalentinax: was just trying to get some assisted pull-ups in today at the rack. hooked my thick green resistance band up to the top bar and stepped my white sneakers securely into the loop. had the older gentleman in the white tee and my other spotter standing right behind me to keep an eye on my form. everything was going smoothly until the band decided it had entirely too much tension. it suddenly snapped and flew back down. the sheer panic on the guys' faces in the background says it all. pretty sure we all had a collective mini heart attack...
