I was looking forward to starting today but I was very intimidated this first day. I am in those days of the month and I was a bit off. Today is a holiday in my city so at midmorning I jumped and I started. I fighted both workouts. I made the extra credit too. While I was stretching I felt really good, I don't know if doing both workouts gave me energy or was the satisfaction of having achieved it. It is hard but not impossible. Now I'm sore but happy. Anyway, I will try to listen to my body and take the breaks I need. This is a tough program and you may need it to get to the end.
