Single Arm Long Arm Planks
- Start in the push-up position.
- Spread your feet wide and take one hand off the ground, placing the arm alongside the body.
- The key is to keep the hips still and square.
- According to Rivera, the arm that's off the ground forces the opposite side to work harder and stabilize.
- Hold for 30 seconds each side.
- Repeat moves 1-5 again to complete the 10-minute EMOM circuit.
