This move strengthens your upper body and core, said Lauren Griffith, ACE-certified group fitness instructor. You'll find that at a higher tempo, the dynamic, compound movement will get your heart rate going as well.
- Start in the high plank position on your hands and toes with your body in a straight line.
- Lower yourself down to your elbows one arm at a time, engageing your core and keeping your back flat.
- Slowly lift back up to your hands with control.
- This counts as one rep.
