The supine bridge is an exercise mostly for beginners that helps teach you to
activate your gluteal muscles. Adding the BOSU balance trainer to the mix
increases the demand for muscle recruitment which can improve results over time
by forcing the neurological system to increase muscle recruitment. The BOSU
supine bridge showed here is a static hold but it can also be turned into a
dynamic hip extension movement by lowering the hips downward and raising them
back up for multiple rep sets.
