Well I really hurt my calf during Day 2 of Insanity. So I am pausing on my workout for now. I will see how my calf is on Monday night, if then its good to go, I will then resume my workout but will start back on Day 2 cycle (since Day 1 is just the Fit Test). Even with proper stretching it did not stop my calf from cramping up and then I did like Shaun T stated and dug deeper and pushed through it, that will be the last time I do that because my right calf feels like I have a permanent “charlie horse.”
I am not giving up though, I really want to do this, but also as Shaun T says, if you hurt, stop the workout.
