Exercise guide

Kettlebell Alternating Swing

  • Intermediate
  • Compound
  • Rep-based
  • Back

The Kettlebell Alternating Swing is a dynamic hinge movement that builds explosive power in the posterior chain while challenging core stability and coordination through hand-to-hand transfers. It effectively targets the glutes and hamstrings while the unilateral load forces the obliques and traps to stabilize the torso.

Equipment

  • Kettlebell

Setup

  1. Stand with your feet slightly wider than shoulder-width apart, with the kettlebell on the floor about a foot in front of you.
  2. Hinge at the hips with a flat back and grip the kettlebell handle with one hand using an overhand grip.
  3. Tilt the kettlebell toward you and engage your lats by pulling your shoulder blade back and down, keeping your free arm out to the side for balance.

How to do it

  1. Hike the kettlebell back between your legs, then explosively drive your hips forward to swing the bell up to chest height.
  2. At the peak of the swing where the bell feels weightless, reach forward with your free hand and switch the kettlebell from one hand to the other.
  3. Allow the kettlebell to fall back between your legs while hinging at the hips, keeping the working arm close to your body.
  4. Exhale sharply as you snap your hips forward to drive the bell up; inhale as the bell descends back into the hinge.

Form checklist

  • Maintain a neutral spine and avoid rounding your lower back during the hinge.
  • Drive the movement entirely from the hips; your arms should act only as pendulums.
  • Switch hands only at the highest point of the swing (the 'float' phase) to ensure control.
  • Keep your core braced and shoulders square to prevent the weight from rotating your torso.

Pro tips

  • Focus on the 'float' phase; the bell should feel weightless for a split second, which is the safest and most efficient time to perform the hand-to-hand transfer.
  • Keep the non-working arm active and synchronized with the movement to help maintain balance and generate more power.

Make it harder

  • Increase the weight of the kettlebell to further challenge your grip strength and posterior chain power.
  • Incorporate a lateral step during the swing to increase the demand on your frontal plane stability and coordination.
