Start with your body in basic crunch position. Take the right leg and bring it over the left. Extend the left
leg, and crunch up, bringing that left knee to the chest. Do 15 reps, pulse for 10. Repeat twice, switch legs.
Combine this with hip thrusts, V-sits, and isometric ab holds, to form a circuit. You will repeat this circuit
4 times. 20 reps for hip thrusts, 15-20 reps for V-sits, and 15 reps for isometric ab holds. For a beginner/older
class, change it up, performing two sets of each exercise to failure.
GOOD LUCK!
