Lay on your back. Bring your legs up and hands up straight in the air. This is your 'Return Point.' Slowly lower your LEFT leg to the ground and your RIGHT arm towards the ground above your head. Come close to the ground but do not touch. Slowly bring them back to the 'Return Point.' Then switch. Lower your RIGHT leg and your LEFT arm in the same fashion. Slowly bring them back to the 'Return Point.' Repeat.
