I have a little problem. After loosing 45kgs I thought what the hey I want those 6 pacs that everyone keeps going on about. So 6 times a week mostly I do 50 v-sit ups 50 each side side crunches on those ab roller things and 100 russian twist things (where you balance on your backside legs and torso in the air holding weights (i use 13kgs) twist from one side to the other)
Then after all that I go for a 4-5km run and I do 4 30 second sprints when jogging. Ive been doing all this for a few weeks and I havent noticed a change. Also I used to do this a few months ago for alot longer with still no sucess. I dont think its a layer of fat because If I lost anymore weight id probably be very underweight.
