SINGLE-LEG GLUTE BRIDGE
Lie on your back with your feet flat and your legs bent. Raise one leg off the ground, pulling your knee to your chest. This is your start position. Using the foot on the floor, drive through your heel to extend your hips upward. Extend your leg as far as possible, pause and then return to the start position to repeat.
SAFETY TIP Be careful not to strain your neck when doing this move
