As alot of you know I have been back on the road to getting into shape once again, all in all it is going good. But today I stated to cramp along the upper stomach while kicking and stretching. I upped my crunches on the ab lounger from 4 sets of 25 to 4 sets of 50. Could this be the problem to much of a jump? I drink plenty of water and I only eat some fruit before working out. This cramp is the mother of all cramps that I have ever had, any advice is appreciated.
