BETTER THAN SQUATS: The largest muscle group in your body (glute muscles) can be the laziest and most difficult to activate. The COBA Glute trainer is proven to increase glute muscle activation faster, safer and more effectively. Itis the only portable piece of equipment in the marketplace with functionality to work the gluteus maximus, gluteus medius and gluteus minimus. You can squat until you drop but you won’t achieve these unparalleled benefits.
