Kettlebell Windmill

CoreKB

A StrongFirst hallmark movement — a kettlebell held locked out overhead while the body hinges laterally at the hip, reaching the opposite hand toward the floor. It trains the core to control multiple planes at once: resisting lateral flexion, controlling thoracic rotation, and stabilizing the loaded shoulder overhead.

Reps

5 per side

Rest

1 min

Contraindications

Shoulder instability overhead or hamstring inflexibility — master the bodyweight version first.

Setup

Press or clean a kettlebell overhead to full lockout on one side. Feet angled roughly 45 degrees, the foot under the kettlebell turned out.

Execution

  1. 1Shift the hip under the kettlebell back and up
  2. 2Keep the arm holding the kettlebell locked out and vertical throughout
  3. 3Hinge the free hand down the inside of the front leg, rotating the torso
  4. 4Do not laterally flex the spine — the motion comes from the hip hinge and thoracic rotation
  5. 5Reverse the motion back to standing under control

Key cues

  • Shift and lift the back hip first
  • Keep the kettlebell arm bolted vertical
  • Rotate the ribcage, don't just bend sideways
  • 70/30 weight distribution favoring the back leg

Common faults

  • Laterally flexing the spine instead of hinging and rotating
  • Kettlebell arm drifting out of vertical alignment
  • Rear heel rising off the floor
  • Going deeper than current mobility allows, forcing compensation
  • Rushing the descent instead of a slow controlled reach

Tweaks

  • Start with a low windmill using just bodyweight or a light object
  • Reduce depth as a regression
  • Progress load gradually once the movement pattern is clean

Regressions

Muscles

Primary: Obliques, Glutes, Hamstrings

Secondary: Shoulders, Erector Spinae

Notes

MULTI-PLANE: primarily ANTI-ROTATION and ANTI-LATERAL FLEXION with a controlled ROTATION component through the thoracic spine. Flagged as cross-category per task instructions.
