Exercise guide

Kettlebell Alternating Press

  • Intermediate
  • Compound
  • Rep-based
  • Shoulders
  • Upper arms

This compound movement builds overhead strength and stability while challenging the core to resist rotation as you alternate sides. It emphasizes the anterior and medial deltoids while requiring significant triceps and serratus anterior engagement for lockout.

Equipment

  • Kettlebell

Setup

  1. Clean two kettlebells to the rack position, holding them against the outside of your forearms with elbows tucked and fists near your chin.
  2. Stand with feet shoulder-width apart, knees slightly soft, and glutes squeezed to create a stable base.
  3. Maintain a neutral spine and brace your core as if preparing for a punch.

How to do it

  1. Exhale as you press one kettlebell vertically, rotating your wrist so your palm faces forward at the top of the movement.
  2. Reach full lockout at the top, ensuring your bicep is close to your ear and your shoulder is packed down.
  3. Inhale as you lower the kettlebell back to the rack position under control, then immediately repeat the movement with the opposite arm.
  4. Maintain a steady, controlled tempo of approximately 2 seconds for the ascent and 2 seconds for the descent.

Form checklist

  • Keep your forearm vertical throughout the entire pressing phase to maximize force transfer.
  • Avoid leaning to the side or arching your lower back to drive the weight up.
  • Keep the non-pressing kettlebell held firmly in a tight rack position; do not let it sag or rest on your shoulder.
  • Ensure your knees remain still—this is a strict press, not a push press.

Pro tips

  • Visualize 'corkscrewing' your arm into the sky to engage the rotator cuff and stabilize the shoulder joint.
  • Squeeze the handle of the resting kettlebell as hard as possible to create irradiation, which increases neural drive and strength in the pressing arm.

Make it harder

  • Perform the exercise from a tall-kneeling position to remove leg stability and further challenge the core.
  • Add a 3-second isometric hold at the peak of each repetition to increase time under tension.
