Glutes are the engines that power your body as it walks, sprints, jumps and kicks. The glute is made up of three muscle groups: gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur. This makes them part of the connective tissues that keep the upper and lower body functioning as a whole, indivisible unit. Strong glutes make you less prone to fatigue from physical exertion. They significantly contribute to developing explosive power in the lower body and act as one of the conduits that transfer power from the lower body to the upper one. All, in all, strong glutes help you move more confidently and be in greater control of your body. The Glutes of Steel Challenge helps you achieve all this in an incremental, month-long, daily practise.
