4 Exercises You Should Never Do
this one puts unnatural strain on your knees
*a man is doing leg extensions on a machine*
this one will hurt your shoulders if done incorrectly
*man is doing behind the back overhead pull down*
this one is a whole lot of work if you do it right
*man is doing squats with weights*
don't ever do this one. IT WILL KILL YOU
*man is at a machine and there is a big spike pointing right at his head as he holds the bar*
