How to do the Stool Plank Jack

  1. Place a padded stool on a stable surface to prevent it from moving.

  2. Stand in front of the stool and then bend over to place your hands on the edge of the stool, a bit wider than shoulder-width apart.

  3. Step back into a plank position with your feet together, your body straight from head to heels, and your shoulders directly above your wrists.

  4. Engage your core to keep your body level and prevent your hips from sagging or piking up throughout the movement.

  5. Jump your feet outward to a bit wider than hip-width apart, similar to a jumping jack motion, while keeping your upper body stable.

  6. Quickly jump your feet back together to return to the starting plank position.

  7. Repeat the jumping motion for the desired number of repetitions, maintaining a strong plank form throughout the set.

Remember to breathe steadily during the exercise, exhale during the exertion phase when jumping out, and inhale as you jump back to the starting position. As with all exercises, start with a lighter intensity to master the form before increasing speed or duration.
