Insanity Calorie Count and Problem?
Hi Guys, So I just started Insanity today and I did Cardio Abs. Thing is when I was doing it I felt the burn, but afterward s when you're supposed to be "dying and light-headed" I was totally fine. Is something wrong with me? I do work out regularly, so is it like an "immunity" to certain work outs or is that Insanity…
