Lie on your back with one leg straight and the other leg slightly bent with your heel on the floor.
Lift the straight leg off the floor to align with the thigh of your bent leg.
Then push through your heel and lift your hips from the floor.
At the top of the movement, you should have a straight line between your shoulders, hips, and knees and your hips should be level.
Return to the starting position and repeat.
