Do This 4 Minute Belly And Thigh Fat Burner (NO Weights)
This total-body workout uses super-fast bodyweight moves to torch calories and tone muscles in whatever time you have.
The key is going all-out. Perform the first exercise at your max intensity for 50 seconds, rest for 10 seconds, and then move to the next exercise (again, as hard and fast as you can).
After completing all five exercises, we guarantee you'll be sweating. If you have more time, rest for a minute and then complete the circuit two or three more times.
