Get down onto your hands and knees on the floor.
Gently raise your left leg backward until your foot is above the plane of your back. Raise it as high as your flexibility allows with the goal being to get your thigh parallel to the floor.
Then slowly return the leg to the starting position to complete one repetition. Repeat 9 more times to complete one set of 10 repetitions. Then repeat 10 times on the opposite side.
You’ve completed this one! Great job!
