This move works your abs, glutes, triceps, biceps, and back all in one exercise. You'll need a set of dumbbells for this.
- Begin on your hands and knees, with your hands right under your shoulders, and your knees directly under your hips. Engage your abs and try not to arch your back (it'll be hard to balance).
- Grab one of your dumbbells and place it in the crease of your right knee. Hold the other one in your left hand.
- At the same time, while keeping your knee bent, lift your right foot up to the sky, and pull your left hand up towards your chest, keeping your arm close to the side of your body. Then slowly lower your hand and knee back towards the ground.
- Repeat for a total of 12 to 15 times. Then do it on the other side.
