Lie on your side.
Lean on your elbow, with your forearm out to the front.
Place the other hand behind your head and lift your hips up into a plank.
Make sure the upper arm makes an angle of 90 degrees with your body and you can make a straight line through your legs and spine.
Keep your pelvis straight, do not allow the upper pelvis to turn to the front or back.
Now raise your upper leg off the floor.
Move back into the side plank position in a slow and controlled movement.
Repeat the exercise.
