is it to good to sit on the box? isn't that hard on the back if you go down and then sit on it then go back up? shouldn't you just tap the box then back up? just curious cause i was watching someone in the gym who i thought was gonna snap their 130lb spine as they sat on the box. i didn't say anything cause i wasn't sure i don't feel comfortable offering advice n the gym.
if its a safety issue do you guys normally speak up and help someone?
