Kettlebell Windmill

A rotational stability exercise that combines an overhead kettlebell lockout with a hip-hinge and trunk rotation to develop shoulder strength, core control and mobility.

Setup

  1. 1. Stand with feet slightly wider than hip-width.
  2. 2. Press the kettlebell overhead on one side, locking out the elbow.
  3. 3. Turn both feet slightly away from the kettlebell side.
  4. 4. Engage the core and keep the kettlebell stacked directly above the shoulder.

Execution

  1. 1. Push the hip on the kettlebell side backwards.
  2. 2. Slide your free hand down the opposite leg, rotating through the trunk.
  3. 3. Maintain the kettlebell directly overhead with a vertical forearm.
  4. 4. Lower as far as mobility allows while keeping the spine long.
  5. 5. Drive through the hip to return to standing.

Coaching cues

  • Stack wrist over shoulder.
  • Push the hip back, not sideways.
  • Rotate through the ribcage, not the lower back.
  • Keep your eyes on the kettlebell for stability.

Common faults & fixes

  • Fault: Shoulder collapses under load.
  • Fix: Reduce weight and practise overhead holds.
  • Fault: Athlete bends rather than hinges.
  • Fix: Cue “push your hip back” and limit depth initially.
  • Fault: Kettlebell drifts forward.
  • Fix: Lock in the lat and keep elbow fully extended.

Regressions

  • Reduce ROM and hinge only to knee level
  • Use a lighter kettlebell
  • Perform a bodyweight version before loading

Variations

  • Bottom-up kettlebell windmill
  • Double kettlebell windmill
  • Bodyweight windmill
  • Dumbbell windmill

Programming ideas

  • 3–5 reps per side for strength
  • 8–10 reps per side for mobility
  • Pair with overhead carries or Z Press for shoulder stability days
  • Include in warm-ups for rotational sports or HYROX prep

Safety

Avoid excessive rotation through the lumbar spine. Use a lighter load when learning the movement. Control the descent and avoid sudden shifts in weight.

Competition standards

No official competition standard. Maintain vertical alignment of the kettlebell throughout the movement. Depth should never compromise spinal position.

In depth

The kettlebell windmill is one of the most effective functional movements for training overhead stability, core rotation and hip-controlled hinging. Because the kettlebell windmill loads the body asymmetrically, every rep challenges your ability to stabilise, rotate and move with precision. This makes it especially valuable for athletes who want better shoulder resilience, improved trunk control and stronger multi-plane movement.

The kettlebell windmill begins with the kettlebell locked overhead. From this position, the athlete hinges at the hip, rotates through the trunk and lowers their free hand towards the floor while keeping the kettlebell stacked directly above the shoulder. This encourages strong shoulder stabilisation, a powerful lat connection and deep oblique engagement. The movement also teaches improved hip mobility, which carries over to lunges, carries, sandbag lifts and other exercises within the RB100.Fitness exercise library.

Athletes preparing for HYROX events often overlook rotational stability, yet it plays a key role in controlling movement under fatigue. The kettlebell windmill develops this control exceptionally well. You can also pair it with exercises such as the Kettlebell Snatch, Dumbbell Z Press or Sandbag Over Shoulder to reinforce overhead strength through different planes. For additional guidance on rotational strength, explore the Rotational Power Series inside the RB100 Exercise Library.

Primary & Secondary Muscles Worked

The kettlebell windmill targets the obliques as the primary rotational stabilisers. The shoulders, especially the deltoids, act as the overhead support mechanism while the glutes and hamstrings drive the hip hinge. The core, lats, triceps and erectors provide rotational control and help prevent collapse under load. Altogether, the movement trains a unique blend of strength, mobility and structural stability.

Because the kettlebell windmill challenges the body across multiple planes, it is an excellent accessory movement for improving balance, structural strength and injury resilience. Whether used in warm-ups, strength blocks or conditioning sessions, it rewards athletes with better movement quality and greater control throughout the entire kinetic chain.
