I'm having this difficulty while doing crunches, sit ups. My abs didn't feel a thing whenever i pushed through crunches and sit ups, but my back hurts a lot.
I used to be active basketball and soccer player, having crunches and sit ups everyday for 200x a day. But now i cant even get through 10 cycles. I have a strong back and maybe i used to put all of my weight in my back, is that a problem? And how to fix this? I've read a lot but its just very hard to make my low back muscles to relax while doing abs workouts. Anyone care to help me pls?
There are a few core exercises that are bad (increased likelihood of injury) for the back, and they're actually most of the typical ab exercises everybody does like situps & crunches. You may have even done some damage back in the days of doing so many.
Do some more research into back friendly core exercise. I know that plank is one, but it's a good idea to read up on planking too, to make sure your actually engaging the core and not transferring the work.
Maybe try :
Leg raises (although those hurt my back so i do just a leg hold, like where I lay down and raise my legs up straight and hold em)
Also: standing core work, like various knee raises and stuff
