Secondary Muscles
A plank variation where hands rest on a medicine ball, increasing core instability demands and shoulder stabilizer activation.
Instructions
- Begin in a plank position with both hands placed on a medicine ball, arms fully extended.
- Maintain a straight line from your head through your heels.
- Keep your core tight and avoid hips sagging or rotating.
- Hold this position for the prescribed time duration.
- Focus on steady, controlled breathing throughout.
- Maintain tension in your entire core, shoulders, and glutes.
Tips
- The medicine ball adds significant instability; start with shorter holds until adapted.
- Keep your shoulders directly over the ball for proper alignment.
- Engage your glutes to prevent your hips from sagging.
- Breathe steadily; do not hold your breath.
- This is an excellent core stability exercise using an unstable surface.
- Progress by increasing hold duration rather than adding movement complexity.
