Plump up your cheeks and tighten your belly using the BOSU!

Complete 10-15 reps on each side for a total of 2-3 sets.

This exercise works both your booty and your core at the same time! Notes on form: - Drive through the heel of the foot on top of the Bosu. - Drive the extended leg straight upward like you're high-5-ing the ceiling with the sole of your shoe.

Hold your posture correctly and you'll love the burn, lose proper posture and you'll hate the ache in your back, so be sure to:

- Squeeze your Glute tight at the top of the bridge and hold tight for the heel tap.

- Keep your extended leg straight and your foot flexed. Imagine you're Hi-5-ing the ceiling with the sole of your shoe.

- Pull your lower belly tight as you lower your leg for the heel tap. [**If the heel tap hurts your back, you're leg is going too low! Decrease the angle for now and increase it as you gain strength.]
