Each session gets a little easier but it still really kicks my butt. I was reading about it earlier today and a calorie calculator computed that I burn 1067 calories in a 90 minute session. Crazy!
But I'm not only doing it for the physical benefits - I want mental and emotional strength as well. I think it will be a slow process but I'll get there. I'm willing to put in the time and effort, I believe the benefits will be worth it.
