Gluteus Minimus, Gluteus Medius & Gluteus Maximus. The glutes are a foundation of all lower body movements. This means your ability to jump higher, run faster and squat heavier are all dependent upon your ability to generate force from these muscles. But in this stone age we are spending so much time parked on our behinds. It is causing our glute muscles to stop firing, becoming weak and undertrained, leaving you with a butt as flat as a pancake accompanied by other surrounding muscles taking the workload instead. We need to target our bodies largest and most powerful muscle group by executing these glute developing movements.
