The TRX squat and reach works your legs and glutes.
TRX Squat and Reach Form Cue
Step away from the TRX base point, holding onto the strap with one hand. Sink down into a squat (chest lifted, and weight in your heels), as you tap your free hand to the floor. As you exhale to rise, squeeze your glutes, and “chop” your non-TRX hand to the TRX. This is one rep.
