Uneven Bars Basics: Grips, Kips, and Casts

Written by Aleena Zuberi · Approved by Sophina Dejesus · Published Aug 24, 2026 · 7 min read

Uneven bars is the most technical event in women's gymnastics; it blends strength, swing timing, and release-and-regrasp skills that don't work quite the same way on any other apparatus. Coaches call out kip, cast, clear hip, and flyaway like it's a second language, and a gymnast can run through all four in about six seconds.

This guide translates the vocabulary, explains what the grips are for, and walks through how the event is scored, so the next time you hear "she stuck her flyaway," you'll know exactly what happened.

What Are Uneven Bars in Gymnastics?

Uneven bars, sometimes called the asymmetric bars, are a women's event built around two horizontal bars set at different heights. According to NBC Olympics, the high bar sits around 2.5 meters, roughly 8 feet, and the low bar sits at about 1.7 meters, roughly 5 feet 5 inches.

The distance between the two bars adjusts, generally somewhere between 1.3 and 1.8 meters, which lets coaches set the gap based on a gymnast's height and the specific release-and-catch skills in her routine.

The bars themselves are engineered for both flex and grip. NBC Olympics describes a fiberglass core wrapped in birch wood laminate, which gives the bar enough give to help gymnasts build swing momentum without feeling unstable.

Olympics.com puts the bar diameter at 4 centimeters, narrow enough for smaller hands to get a full grip around it. The event itself descended from men's parallel bars: NBC Olympics notes that gymnastics federations raised one bar in the 1930s to create room for the swinging and release skills that define the modern event.

What Are Uneven Bars in Gymnastics?

Grips are leather or synthetic strips that wrap across the palm and buckle around the wrist, and their whole job is friction and protection. Bare skin against a wooden bar during hours of swinging practice tears fast, and grips spread that load more evenly across the hand. The American Academy of Pediatrics describes two general categories:

• Basic palm protector: for gymnasts just starting bar work
• Leather dowel grips: add a wooden dowel across the palm for a more secure hold, used once a gymnast reaches more advanced release and swing skills

Timing matters here, and it isn't a parent's decision to make alone. A coach typically waits until a gymnast's bar skills involve enough friction and load- think consistent kips, casts, and swings- before introducing any grip at all.

Handing a beginner a pair of dowel grips before she has the hand strength and swing technique to use them safely just adds risk without a clear need. If your gym's coaching staff hasn't brought up grips yet, that's not an oversight. It usually means the current skill set doesn't call for them.

Kips, Casts, and the Language of Bar Strength

Two terms explain almost everything you'll hear during a bar's rotation: kip and cast.

• Kip: from a hang below the bar to a support position above it, using a whip of the hips and legs rather than an arm pull
• Cast: from a support position above the bar into a swing, pushing the hips and legs up and away from the bar on straight arms

A kip looks deceptively simple and is one of the more physically demanding basic skills a gymnast learns on bars, which is why coaches spend time on the glide, the hip snap, and the arm push that make it work before ever calling it "clean." How high a gymnast casts, whether her hips clear horizontal or barely lift off the bar, is one of the clearest outward signs of her bar strength.

Level 4 vs. Level 5 bars, per BeamIQ's illustrative level guides for USA Gymnastics' Development Program:

• Level 4 — glide swing (a related, more basic skill that doesn't yet require the hip-snap of a true kip)
• Level 5 — glide kip, cast above horizontal, clear hip circle, flyaway dismount

This is context for understanding what a coach means when she tells a parent "she's still working on getting her cast above horizontal" instead of a vague "she's doing fine on bars."

For the athlete reading this:

If your gymnast's kip looks like an arm-strength problem, it's usually a timing problem. The glide, the hip snap, and the push happen in sequence, and a coach who keeps sending her back to drill the glide by itself isn't being repetitive without reason.

How Uneven Bars Is Scored

Bars follows the same two-score format as every other women's artistic gymnastics event. Olympics.com explains that each skill in a routine is assigned to a value group, starting at "A" for the easiest elements worth 0.1, and moving up through higher letters as difficulty increases.

A gymnast's difficulty score adds up her hardest counted elements. Execution, scored separately starting from 10.0, penalizes bent legs, incomplete turns, awkward handstands, and the costliest single error: a fall.

Falls carry an immediate cost on bars specifically. At the elite and international level, NBC Olympics reports that a fall triggers a full 1.00-point deduction, with roughly 30 seconds to remount the bar and finish the routine rather than losing the attempt entirely.

Deduction values and remount windows can differ at the youth Development Program levels, so check your gym's rulebook for the exact number that applies to your gymnast's level. That remount window explains why you'll sometimes see a gymnast fall, visibly reset, and climb straight back up: the clock is already running.

Bar Injuries Parents Should Understand

Bar work loads the wrist in a way few other youth activities do, and it's worth understanding why. The American Academy of Pediatrics reports that weight-bearing skills can put two to four times a gymnast's body weight through the wrist joint, repeatedly, across a single practice. Growth plates in a young athlete's wrist are still developing cartilage rather than solid bone, which makes them more vulnerable to that repeated compression than an adult's would be.

That repeated loading has a name in sports medicine: "gymnast wrist," clinically described as distal radial epiphysitis. A peer-reviewed overview in Current Sports Medicine Reports traces the injury to repeated axial loading and hyperextension on that still-growing plate, and recommends a minimum of six weeks away from weight-bearing activity once a gymnast is diagnosed. That's a meaningful chunk of a season, and it's why catching wrist pain early matters more than pushing through it.

The prevention side is straightforward and worth repeating to any gymnast who says her wrist "just aches a little." The American Academy of Pediatrics recommends a gradual increase in training intensity, following the coach's skill progression instead of rushing ahead, a proper warm-up before bar work, and wrist braces when a coach or physician recommends them.

Wrist pain that lingers past a day, or shows any swelling, isn't a "shake it off" situation. It's a next-day doctor visit, full stop.

Frequently Asked Questions

What is a kip on uneven bars?

A kip is the move that takes a gymnast from hanging below the bar to sitting or supporting above it, using a whip of the hips and legs rather than pulling with the arms. It's usually the first big-strength skill a gymnast learns on bars and shows up at Level 5 in USA Gymnastics' Development Program.

What are gymnastics grips for?

Grips protect the palms from tearing and give a gymnast a more secure hold on the bar during swinging and release skills. Beginners typically start with a basic palm protector, and coaches introduce dowel grips, which add a wooden bar across the palm, only once a gymnast reaches more advanced bar work.

How high are uneven bars?

The high bar sits around 2.5 meters, about 8 feet, and the low bar sits around 1.7 meters, about 5 feet 5 inches. The distance between the two bars is adjustable, generally somewhere between 1.3 and 1.8 meters, so coaches can set the gap to match a gymnast's height and the skills in her routine.

Do beginners need grips on bars?

Not always right away. Many programs start young gymnasts bare-handed on lower-intensity bar work and introduce a basic palm protector once swinging and pullover-style skills increase hand friction and load. The right timing is a coaching decision, not something to guess at from a gear catalog.

What is a cast in gymnastics?

A cast is when a gymnast, supporting her body weight on top of the bar with straight arms, pushes her hips and legs up and away from the bar before swinging back down. Casting higher off the bar, eventually above horizontal, is one of the easiest things to watch for if you want to track a gymnast's bar strength from level to level.

Why do gymnasts fall off uneven bars?

Bars combine grip strength, timing, and release-and-catch skills, so a small error in any one of those compounds fast. At the elite level, a fall costs a full point under FIG scoring rules, and gymnasts get roughly 30 seconds to remount and continue the routine rather than losing the whole attempt. Deduction values can differ at the youth Development Program levels.

Where to Go From Here

Bars rewards patience. The kip, the cast, and every release skill after it build on hand strength and timing that take seasons to develop.

If your gymnast is deep in that process right now, how gymnastics skills progress from level to level lays out what that timeline generally looks like across all four events, and vault basics covers the apparatus most gymnasts learn alongside bars.

For the bigger picture of what a season in the sport involves, start with the youth gymnastics parent guide, or look into gymnastics programs built around this kind of progression.
