Oblique Crunches with Extended Legs

Start by lying on your side with one forearm down and your knees slightly bent. Roll slightly back onto your glutes (like you are sitting on the back pocket) and lift your legs a few inches off the floor. Reach the other arm high into the air.

Contract your core as you reach your toes up to your hand squeezing at the waistline.

Slowly lower your legs and lift your arm to return to the starting position. Repeat the exercise according to the training plan then switch sides.
