Ring Single-Arm Pull-Up
What Is the Ring Single-Arm Pull-Up?
Ring Single-Arm Pull-Up is a compound exercise that primarily targets the back and also engages the biceps, forearms, rear shoulders and core. It is an advanced-level movement in which you pull your full body weight up to a single gymnastics ring with one arm while the other arm hangs free at your side.
The one-arm pull-up is treated as a milestone of relative pulling strength in calisthenics and climbing, and it is rare even among well-trained people. In a study of advanced rock climbers, only two of the 14 who took part in the one-arm condition could do four to five unassisted reps on a bar, and the rest trained the movement with a band taking part of their weight.
The latissimus dorsi and teres major drive the arm down to your side, while the biceps, brachialis and brachioradialis bend the elbow under a load no two-arm pull-up asks of them. Your grip has to hold the entire body, and because the weight hangs off one side, the obliques and the rest of the core work hard to stop the torso from spinning. The ring turns freely, so your hand and forearm can rotate through the pull, usually from palm facing forward at the bottom to palm facing you at the top, which many coaches find easier on the elbow than a fixed bar.
This exercise suits advanced trainees who already own strict two-arm pull-ups for high reps and want to keep building pulling strength without adding external load. If you are not there yet, build up through the Ring Pull-Up, the Ring Archer Pull-Up and the Band-Assisted Ring Single-Arm Pull-Up, which lets a band take part of your weight while you learn the one-arm pattern.

Instructions
- Set a ring high enough that you can hang with your arm fully straight and your feet clear of the floor.
- Grip the ring with one hand, thumb wrapped around it, and hang with the arm straight overhead and your free arm relaxed at your side.
- Keep your legs together with the knees slightly bent and your feet off the floor.
- Without bending the elbow, draw your shoulder down away from your ear to set the shoulder blade.
- Brace your abs and squeeze your glutes and legs so your body does not spin.
- Pull by driving your elbow down toward your ribs, letting the ring turn so your palm rotates toward you as you rise.
- Keep pulling until your chin reaches the height of the ring, with your hand beside your chin and the elbow tucked in at your side.
- Pause briefly, then lower yourself under control over two to three seconds until the arm is straight again, keeping the shoulder set.
- Finish your reps, then switch arms and do the same number on the other side.
Common Mistakes
Skipping the base
Attempting full reps before strict two-arm and archer pull-ups are solid overloads the elbow tendons long before the muscles give out.
Hanging passively
Relaxing the shoulder at the bottom leaves the joint hanging on its tendons and ligaments instead of being held in place by the lats and shoulder blade.
Kipping into the rep
A leg kick or swing to start the pull skips the hardest range and throws the load onto the elbow and shoulder at unpredictable angles.
Letting the body spin
A loose core and legs let the torso rotate away from the working arm, which leaks force and stalls the pull.
Dropping on the way down
Falling through the lowering phase instead of controlling it jolts the elbow and shoulder at the bottom and wastes the strongest part of the rep.
Cutting the range short
Stopping before your chin reaches ring height or before the arm is straight again at the bottom turns full reps into partials.
Injuries
Ring Single-Arm Pull-Up is a high risk exercise when performed with proper technique. Your entire body weight hangs from one hand, so the biceps tendon at the front of the elbow, the tendons on the inside of the elbow and the rotator cuff all take near-maximal loads, most of all in the straight-arm bottom position. Tendons adapt more slowly than muscle, and elbow tendon pain is the most common setback for people chasing this skill.
Build up to it over months rather than weeks, and keep sets short and weekly volume low once you start. Set the shoulder by drawing it down away from your ear before every pull, lower under control instead of dropping into the hang, and let the ring rotate with your hand rather than fighting it. Never kip or swing into a rep, since the momentum lands on the elbow and shoulder at unpredictable angles.
If full reps are out of reach, regress to the Band-Assisted Ring Single-Arm Pull-Up, the Ring Archer Pull-Up or the two-arm Ring Pull-Up. Once clean reps come easily, pauses at several heights and slower lowering add difficulty before any extra load does.
Stop the set if you feel sharp pain at the front or inside of the elbow or at the front of the shoulder, or if your grip starts to fail. Pain that lingers into the next day is a sign to cut volume, and a sudden pop or sharp pain near the elbow crease needs a medical check before you train the arm again.

Frequently Asked Questions
- Q: How strong do I need to be before trying a single-arm pull-up on rings?
Coaches usually look for strict two-arm pull-ups for high reps, comfortable weighted pull-ups and clean archer pull-ups first. If you cannot yet lower yourself slowly on one arm, stay with the Ring Archer Pull-Up or the Band-Assisted Ring Single-Arm Pull-Up.
- Q: Is a single-arm pull-up easier on rings or on a bar?
The strength it takes is about the same, but the ring turns with your hand so the forearm can rotate naturally through the pull, which many people find easier on the elbow. In exchange, the ring can swing and spin, so it asks for more body control than a fixed bar.
- Q: Why does my body spin during the rep?
Your weight hangs off one side, so the body wants to rotate around the working arm. Brace your abs, squeeze your legs together and drive the elbow down toward your hip, and a slight turn toward the working arm at the top is normal.
- Q: Does holding my working wrist with the other hand count?
No, not as a full rep. Holding the wrist or forearm lets the free arm take part of your weight, which makes it a useful stepping stone, but log those reps separately from unassisted ones.
- Q: How should I program it?
Keep reps low, usually one to three per set, rest fully between sets and train each arm for the same number of reps. Start with your weaker arm, and one or two sessions a week is plenty given how much load the elbow takes.
