Popular Core Workouts

Trainer Gregory Joujon-Roche uses this popular core workout for his celebrity clients:

Accordion Crunches

Gregory Joujon-Roche says that Accordion Crunches work your upper abs and lower abs. By focusing on lifting your legs off the ground so much, you especially work your lower abs. Do as many as you can. Go slow, squeeze your abs on each one. Write down how many you perform, so that you can break your record next time.

Side Bridges

Use the Side Bridges to work your abs, back, and glutes. Use your elbow point and shoulder point for support. Hold for 30 seconds to a minute if you can.


Finish the workout with Supermans, or as Greg calls them, Superheroes. Here’s another trainer’s demonstration of the Supermans:
