The TRX Side Plank is an incredibly effective and demanding exercise that requires complete core coordination and tremendous strength from the quadratus lumborum and obliques. You can regress the TRX Side Plank so that it can be used for de-conditioned clients.
Adding hip abduction to the standard TRX Side Plank is a very demanding action that builds hip stability and glute strength and endurance.
