abdominals and cramps

lately ive been doing sit-ups etc for my abdominals but evertime i get a bigg cramp on my abbs and i look like a right fool because it looks like im having a fit since i have to stretch as much as possible to make the cramp go away.
 
anyone maybe know a reason or any information at all..
 
has it happened to you?
 
todays cramp was veryyyyy painfullll
 
thanks

try adding more pottassium to your diet.. couple of bananas a day should do it

also keep well hydrated

I sometimes get the same thing.

Last time i got this i was just sitting on my computer chair, lent over to pick something up i dropped and the cramps were ridiculous mate. Couldnt even sit up for 5 minutes.

thats the one stevo- they bloody hurt!!.... i found out after that it was due to dyhydration especially as ive been training hard regularly now.

now if i crap i need 700ml water and then il be ok... abit specific i kno but works now lo.. thats for the replies
