Instructions: Repeat each move with no rest in between until the set is done, rest up to 2 minutes and repeat the whole set again 3, 5 or 7 times depending on your fitness level.

What it works: legs, arms, lower abs, glutes, core. This workout does a lot. 

Tip: Use a laundry basket for the lifting exercises. Just aim to get through each one. All you need is tenacity.
