After my miserable failure the other day , i talked to a mate about the challenge and came to the conclusion that i should switch to a lighter regime. Namely column 2.
Redid day 1 in this category, which meant doing 7+7+5+4+>5.
After starting a sharp pain shot through my lower abs and it persisted but i decided that i wouldn't back down , so i clenched my stomach muscles and powered through it. I did them all , it was difficult but at least i didn't collapse after the second set like i did before.
