  • Triceps

  • Serratus anterior
  • Trapezius

Equipment

  • Body weight

Setup

  1. Stand tall with your feet hip-width apart and your weight evenly distributed.
  2. Interlace your fingers with palms facing upward, or keep your hands parallel with palms facing inward.
  3. Engage your core and tuck your pelvis slightly to maintain a neutral spine.

How to do it

  1. Inhale deeply as you reach your arms directly overhead, fully extending your elbows.
  2. Exhale and push your palms toward the ceiling, actively shrugging your shoulders to reach maximum height.
  3. Hold the peak vertical extension for 2-3 seconds while maintaining tension in your triceps.
  4. Slowly lower your arms back to the starting position with a controlled tempo.

Form checklist

  • Keep your ribcage tucked down to prevent excessive arching in the lower back.
  • Ensure elbows are fully locked out to maximize tricep and lat activation.
  • Maintain a neutral neck position, looking straight ahead rather than up at your hands.
  • Keep your shoulders away from your ears until the final reach phase of the movement.

Pro tips

  • Focus on the mind-muscle connection by imagining you are pushing a heavy weight toward the ceiling to increase muscle recruitment.
  • Squeeze your shoulder blades together slightly at the top to stabilize the scapulae while reaching.

Make it harder

  • Perform the stretch while standing on your tiptoes to incorporate calf activation and challenge your balance.
  • Hold a light resistance band between your hands, pulling it slightly outward as you reach upward.
