Sunday Morning Fat Burning Workout

I like to get up early on Sunday morning before the family gets up and get a fat burning workout in. I do this on an empty stomach to raise my metabolism during the day. Since I am having shoulder issues and the Dr. has told me to stay away from upper body work. I saw Jon Hinds owner of Monkey Bar Gym demonstrating two cool exercises with his Power Jumper that I happen to own one myself . So I did my own workout with these two exercises and added one of my favorites the Double Under with a Jump Rope. The Workout was as follows.

4 set of 25
25 Power Jumper Squats
25 Power Jumper Back Extensions
Double under to failure
The video below is  my second set of the four sets
