the first phase is extremely exhausting, like 80 minutes; then the others take 50 minutes, but the intensity is increasing every phase. sure it' hard. but if you want gains, you have to do it no matter how hard a program is.

I won't let myself end where I started. I won't let myself finish where I began. Look me in the eyes. I have something more important more courage. I have patience. I will become what I know I am."
