The Kettlebell Side Plank is a potent lateral stability exercise that integrates oblique strength with shoulder girdle stability. By holding a kettlebell in the top hand, you increase the demand on the rotator cuff and serratus anterior while forcing the core to resist rotational forces.

Setup
- Lie on your side with your bottom forearm flat on the floor, elbow directly under your shoulder.
- Stack your feet or stagger them (top foot in front) for better balance.
- Grip the kettlebell with your top hand and press it straight up toward the ceiling, locking out your elbow.
- Ensure your wrist is straight and the kettlebell is resting on the back of your forearm.
How to do it
- Exhale and lift your hips off the ground until your body forms a straight line from head to heels.
- Maintain a vertical arm position, keeping the kettlebell directly over your shoulder joint.
- Breathe rhythmically into your abdomen while bracing your core and squeezing your glutes.
- Lower your hips back to the floor with control once the set duration is complete.
Form checklist
- Keep the bottom shoulder pushed away from your ear to avoid shrugging.
- Ensure the hips remain stacked and do not rotate toward the floor.
- Keep the kettlebell wrist neutral; do not let the weight bend your wrist backward.
- Maintain a straight line through the neck—look straight ahead or at the kettlebell.
Pro tips
- Actively 'punch' the kettlebell toward the ceiling to engage the serratus anterior and create a more stable shoulder base.
- Drive the edge of your bottom foot into the floor to better engage the glute medius and lateral chain.
Make it harder
- Transition to a 'Bottoms-Up' kettlebell hold to drastically increase the demand on your grip and rotator cuff stability.
- Lift the top leg into a star position to further challenge the glutes and core balance.
