Starting in a plank position, bring your left foot up and around and to the outside of your left hand.
Hold for 5 seconds and bring the foot back into the plank position. Repeat this movement on your right side.
Complete 10 reps on each leg.
Tip: If it is difficult for you to swing your leg up to the above position, start on your hands and knees, then extend your back leg in the lunge position.
