There are times that i hurt so much that i can swear that every bone inside my body feels as if they are breaking along with my heart. I'm barely breathing, i'm falling apart. There is NO pain like a broken heart of a real loving, innocent soul.
Commitment like this needs to be done by someone with body & CRF conditioned to intense interval training. Not to be entered into by a novice as injury will likely occur.(more resting time needed for muscle groups for beginners).
