cable crunches are a lower back exercise

Well, they are the way ~90% of people do them....

if this is you, go do hyperextensions and figure out how to do a real crunch...

it was espescially funny today when i saw a girl go from doing hyper extensions to doing horrible form cable crunches..


All that matter is the weight stack you can move. The muscles you feel triggering are completely irrelevant, said no one, ever
