Are bungie cords good for crunches?

Question

whenever I do normal crunches i don't feel much of a burn, so i like tying a bungie cord around the leg of a heaver table, and holding on to the ends of the bungie cord and do crunches from there. It feels harder to do and i get sore whenever i do it but i was wondering if that's bad for my back or anything.
thnx

Answer 1

Any added resistance increases the workout effectivness, and it will be no worse for your back than regular crunches, in fact it might even help your back.
