How to do Glute bridges
Begin lying on your back with the legs bent at 90-degrees and the arms down at your sides with the palms down.
Lift your hips up toward the ceiling as you press through the heels and squeeze the glutes. Raise the hips until your body is in a straight line from head to knees.
Then, lower the hips back down to the ground.
Repeat for the desired repetitions.
