A glute bridge is an exercise that strengthens the muscles in your buttock and hamstrings. It is important to maintain a neutral spine position, and keep your hips in line with your shoulders.
To perform the exercise, lie on your back with your knees bent and feet flat on the floor. Keep your arms by your sides, palms down. Press into the floor with both feet and use this momentum to lift up one leg until it forms a straight line with the rest of your body. Squeeze both glutes at the top of this movement before slowly lowering back down to start position. Repeat for desired reps then switch legs and repeat for desired reps.
The glute bridge is a great exercise for strengthening core muscles as well as improving mobility in hip flexors, hamstrings, and other lower body muscles.
