Lunging down onto the mat, place your hands shoulder width apart, with your chest over your hands. Extend your legs out behind your body, up on toes and keeping them hip width apart. Drop down to your elbows (may clasp hands). Keep your head inline with your spine looking down and slightly in front of you hands. Bottom up as if you have a basketball under your hips.
Drop your hip to the right as though you are going around the basketball, getting a twist in your torso. Try and maintain strength through your body. Return to the centre then drop to the left side. Return to the centre.
Counting: Right and Left side = 1 rep
Note: If you find you are feeling this in your lower back, lift your bottom slightly to focus more on the core.
