- Intermediate
- Compound
- Timed hold

The stability ball front plank adds an element of instability to the traditional plank, significantly increasing recruitment of the deep core stabilizers and obliques. It forces the rectus abdominis to work harder to maintain spinal alignment against the shifting surface of the ball.

Setup
- Kneel behind the stability ball and place your forearms on the center of the ball with elbows directly under your shoulders.
- Clasp your hands together or keep your forearms parallel to create a stable base.
- Step your feet back one at a time until your legs are fully extended and your body forms a straight line from head to heels.
- Position your feet hip-width apart for balance, or closer together to increase the stability challenge.
How to do it
- Engage your core by drawing your navel toward your spine and squeeze your glutes to lock your pelvis in place.
- Maintain a neutral neck by looking at a spot on the ball or slightly in front of it.
- Breathe steadily and deeply through your nose, maintaining constant tension in your midsection.
- Hold the position for the duration of the set, focusing on keeping the ball perfectly still.
Form checklist
- Do not let your lower back arch or your hips sag toward the floor.
- Push actively through your forearms to keep your shoulder blades from collapsing together.
- Ensure your elbows remain stacked directly under your shoulders to avoid unnecessary joint strain.
- Keep your glutes and quads tight to maintain a rigid, straight-line posture.
Pro tips
- Actively try to 'pull' your elbows toward your toes without moving them to create intense isometric tension in the abs.
- Focus on 'bracing' your core as if you are about to take a punch to ensure the deep transverse abdominis is fully engaged.
Make it harder
- Stir the Pot: While maintaining the plank, move your forearms in small, controlled circles to further challenge your stability.
- Stability Ball Saw: Slowly push the ball forward a few inches using your shoulders, then pull it back to the starting position.
