I imagine it's not that uncommon though just wondered if the obvious reason was the right one - i.e. i need to do more of the exercise to increase muscle endurance/strength etc - diet related?
I tend to do my ab work at the end of a session - typically crunches and unweighted vertical hip raises. I'll do 40 crunches in 2 sets of 20, then roll and do 20 in 2 sets of 10 for my obliques on each side (so 20straight, 20staight, 10left, 10right, 10left, 10right). On the Vertical hip raises, i'll do say 3 sets of 8.
frequently get cramp when doing this... its normally only one ab (middle left) - the other day, it stayed for about 3-5 minutes - deep breaths etc.
Is there a particular reason I cramp on this exercise but not on others???
I don't cramp on chest, biceps, triceps, delts, gluts etc...
Thanks guys and gals!
