Side planks are a great way to work your core, but why not add a twist to spice things up? Adding any kind of motion to a side plank challenges your balance, works your obliques, and tones your shoulders. Needless to say, it's a move you have to try!
- Come into a side elbow plank on your right side, with your feet stacked one on top of the other. Keep your weight on your right elbow with your fingers reaching away from your body.
- Place your left arm behind your head, and inhale to prepare.
- Exhale, and pull your navel to your spine, engaging your deep abs. Rotate your left ribcage toward the floor. Stay there for a second, and deepen your abdominal connection by pulling your navel in toward your spine even more.
- Return to the starting position, and repeat seven more times for a total of eight reps, then switch sides. Repeat series again on your left side.
Bonus: although this is a strength training move, this exercise also provides a nice stretch for your upper back!
