The glutes are a very important muscle for our daily movements including standing up, walking, and going up and downstairs. The bridge exercise is a great foundational exercise for glute strengthening and is a central movement in a lot of exercises. However, form is very important in order to get proper activation and avoid compensations from other regions. The core should be engaged before the movement and slowly bridge up trying to lift one segment at a time. You should not go so high that you feel the muscle in your back engage or feel an arch.
