Am I doing something wrong or do I need to suck it up or is that part of the endurance to this exercise but my arms seems to get tired after 20-25 reps doing bent hollow body rocks. I hold my arms low to my side.
also does it count if I place my hands on my knees when it gets tired and I finish the reps?
Yes, my abs burn tool but Ive those threads and I was wondering if anyone else has this problem. Thanks!
