Kettlebell Single Arm Overhead Lunge
- Advanced
- Compound
- Rep-based
- Lower legs
- Upper legs
This advanced unilateral movement builds exceptional core stability, shoulder mobility, and lower body power by challenging balance and overhead strength simultaneously. It forces the obliques and deltoids to work overtime to stabilize the weight while the legs drive the lunge pattern.

Setup
- Clean the kettlebell to the rack position, then press it directly overhead until the arm is fully locked out.
- Pack your shoulder down away from your ear and ensure your wrist is straight with the bell resting on the back of your forearm.
- Stand with feet hip-width apart, core braced, and eyes fixed on a point straight ahead.
- Position your free arm out to the side or on your hip to assist with balance.
How to do it
- Inhale and take a controlled step forward with the leg opposite to the weighted arm (e.g., if the KB is in the right hand, step with the left leg).
- Lower your hips until both knees are at approximately 90-degree angles, keeping the kettlebell vertically stacked directly over your shoulder.
- Exhale and drive powerfully through the front heel to return to the starting standing position.
- Maintain a controlled tempo, taking 2 seconds to lower and 1 second to drive back up.
Form checklist
- Keep the overhead arm fully locked out and vertical throughout the entire movement.
- Maintain an upright torso; do not allow the weight to pull your chest forward or to the side.
- Ensure the front knee tracks in line with your toes and does not cave inward.
- Keep your core tightly braced to prevent excessive arching in the lower back.
Pro tips
- Actively 'punch' the kettlebell toward the ceiling to engage the serratus anterior and maximize shoulder stability.
- Squeeze the glute of the trailing leg at the bottom of the lunge to stabilize the pelvis and protect the lumbar spine.
- If you feel unstable, narrow your stance slightly but maintain 'train track' foot positioning rather than a 'tightrope' stance.
Make it harder
- Perform a reverse lunge instead of a forward lunge to increase the eccentric demand and stability requirements of the front hip.
- Add a 3-second pause at the bottom of each repetition to eliminate momentum and maximize time under tension.
