Setup

  1. Adjust a single gymnastic ring to a height where you can hang with your arm fully extended and feet clear of the floor.
  2. Grip the ring firmly with a neutral or slightly overhand grip, or use a false grip for better leverage.
  3. Engage your core and squeeze your non-working arm tightly against your side or across your chest to create full-body tension.

How to do it

  1. Initiate the movement by depressing your shoulder blade down and back, engaging the lat before the elbow bends.
  2. Exhale and pull your chest toward the ring, allowing the ring to naturally rotate into a supinated (palm-facing-you) position as you rise.
  3. Continue pulling until your chin is clearly above the ring, then inhale as you lower yourself with a controlled 3-second tempo back to a dead hang.

Form checklist

  • Keep the shoulder of the working arm packed and away from your ear at all times.
  • Maintain a 'hollow body' position with braced abs to prevent the legs from swinging or the back from arching.
  • Ensure the movement is strictly vertical without using a 'kip' or leg drive for momentum.
  • Complete the full range of motion, reaching a dead hang at the bottom of every repetition.

Pro tips

  • Use a false grip—resting the heel of your palm on top of the ring—to shorten the lever arm and increase bicep mechanical advantage.
  • Focus on pulling the ring 'down' to your shoulder rather than pulling your body 'up' to the ring to maximize lat recruitment.

Make it harder

  • Add a weighted vest to increase the total load once you can perform 3-5 strict reps with body weight.
  • Incorporate an isometric hold at the top of the movement for 2-3 seconds to maximize time under tension.
