1. On all fours, hands over shoulders, knees over hips.
2. Start with your left knee on ground, lift and push your right foot behind you and then bend your knee to bring your right knee up and around in a circular manner to rejoin the same position as left knee - bent and on the ground.
3. Repeat 5 repetitions on the right and then 5 on the left.
Once per day and those hips and low back will thank you for it :)
