I managed to do 75 sit-ups continuous. Not at 100 yet. My abs muscles are very tiny right now. I also managed to do 30 continuous push-ups. Not the typical 50-60 continuous I used to do.
Anyway, my legs are shrinking in size. They are at 19" girth. That's pityful compared to their former 24" glorious thunders. No I have not been doing any kinds of sqauts. I need to load up on that routine.
