Secondary Muscles
A side plank variation with a medicine ball on the hip or on the upper body, intensifying oblique and lateral core stabilizer engagement.
Instructions
- Lie on your side with your forearm on the ground, elbow directly under your shoulder.
- Place a medicine ball on your hip or upper body.
- Push through your forearm to lift your hips off the ground, forming a straight line from head to heels.
- Keep your body in a rigid plank position, resisting any rotation or sagging.
- Hold this position for the prescribed time duration.
- Repeat on the opposite side.
Tips
- Keep your core engaged and glutes tight to prevent hip sagging.
- Your body should form a straight line from head to heels.
- Maintain steady, controlled breathing throughout the hold.
- The medicine ball adds load; start with shorter hold durations.
- Focus on stability and anti-rotation rather than any movement.
- This is an excellent oblique and lateral core stability exercise.
