Indoor Climbing Grip Types Explained: Master Every Hold Style in 2026

Your Hand Position Is Why You Keep Falling Off the Same Move

Indoor climbing grip types are not arbitrary categories someone invented to fill out a route setters. They exist because your fingers, palms, and wrists are biomechanically distinct tools that respond differently to force applied at different angles. When you understand how each grip type works, you stop randomly grabbing holds and start making deliberate choices that keep you on the wall longer.

Most climbers develop a dominant grip style and lean on it until it fails them. Usually that failure comes at a plateau, when the problem requires something slightly outside your comfort zone and your hand just does not lock in the way you expect it to. The solution is not more strength. It is better understanding of how each grip type loads your fingers and where the critical contact points actually are.

This article covers every major grip type you will encounter in an indoor climbing gym, from the familiar jug to the finicky sloper, with the technical details about hand placement, wrist angle, and load distribution that most articles skip because they assume readers do not want to hear it. You do want to hear it. That is why you are here.

Jug Holds: The Gateway Grip That Teaches You Nothing and Everything

Jug holds are the wide, positive features that wrap around your hand like a bucket. They are forgiving. They are comfortable. They are also a trap if you let them build bad habits.

The correct way to grab a jug is to get your fingers as deep inside the feature as they will go, with your thumb typically placed on top of the hold for added security. The pad of your palm should make solid contact with the back wall of the hold while your fingers curl around the positive edge. You are essentially choking down on the hold, using your hand like a hook rather than a clamp.

The problem with jugs is that they let you get away with sloppy hand position. When the hold is big enough to catch your whole hand, you can half-ass your grip and still hold on. This creates a feedback loop where you never develop the precision that smaller holds demand. If you have been climbing for more than a year and still drop jugs, examine your hand placement before you blame the bolt or your shoes.

Jug holds are excellent for warming up, for rests between sequences, and for practicing movement patterns you want to ingrain. They are not the place to test your finger strength because they do not load your fingers the way other holds do. Use them intentionally.

Sloper Holds: Learning to Trust Your Hand Instead of Fighting It

Sloper holds are rounded features that slope away from you, offering no positive edge to grip. The force required to stay attached to a sloper comes entirely from friction and the geometry of your palm against the hold surface. If you are grabbing a sloper the way you grab a jug, you will barn door off within seconds.

The key to sloper technique is understanding that your hand position dictates whether friction works for you or against you. Your palm must make maximum contact with the hold surface, and your wrist must be positioned to generate torque that presses your hand into the rock. The direction of pull matters enormously. Slopers reward climbers who match their body position to the direction of force. Climbers who pull straight down on a sloper are working against the one thing that makes the hold usable.

In indoor climbing gyms, sloper holds are often set on steep terrain where body position is the limiting factor. If you are campusing slopers, your body is too far from the wall and your center of mass is in the wrong place. Get your hips closer, get your body more inline with the direction of pull, and feel the hold become stable under your hand.

Most climbers hate slopers because they expose weaknesses in body positioning that we prefer to ignore. The fix is not more sloper training. The fix is better movement literacy, which slopers force you to develop whether you want to or not.

Crimp Holds: Small Edges and the Grading System That Saves Your Tendons

Crimp holds are defined by their positive edge depth. Open-hand crimps have enough depth to accommodate your fingertip pads at a relaxed wrist angle. Full crimps, also called closed crimps, require your thumb to lock over your index finger, which significantly increases the load on your finger flexor tendons and the pulleys that protect them.

The distinction matters because your body cannot tell the difference between a safe load and an unsafe load. You feel the resistance of a hard move and your nervous system recruits as many fibers as it takes to complete the motion. If you are crimping hard on a small edge before your fingers are prepared for that load, you are accumulating damage that will manifest as a pulley strain or a flexor tendon issue at the worst possible moment.

Open-hand crimping should be your default on edges smaller than about 25 millimeters. This grip type distributes force more evenly across your fingers and places less stress on the connective tissue that is most vulnerable to overuse injury. Full crimping should be reserved for situations where open-hand simply will not hold, and you should never train full crimp capacity before you can hang body weight on a 20-millimeter edge with an open hand for at least 15 seconds.

Indoor climbing gyms set problems that require full crimping before you are ready for them all the time. This is not a flaw in the routing. It is a test of whether you will be honest with yourself about what your fingers can actually handle.

Pocket and Two-Finger Holds: Handle With Extreme Prejudice

Pocket holds are holes drilled to specific depths, intended for one finger, two fingers, or in some cases three. The finger you place in a pocket determines the load distribution across your hand and the torque your wrist must counteract. Single finger pockets, also called monos, are the most stressful because one digit bears all the force that your entire hand would normally manage.

Two-finger pockets are typically used with the index and middle finger, which is the strongest configuration because those two digits share a bone on the palm side through the interosseous membrane. Using the middle and ring finger in a pocket reduces your effective strength by about 15 percent compared to index and middle. Ring and pinky pockets are the weakest configuration and should be treated with extreme caution because the ring finger has less independent extensor capability than the others.

The most common mistake on pocket climbing is using fingers that are too close together or too far apart for the pocket depth. A pocket drilled for two fingers expects those two fingers to be adjacent and parallel. If you splay your fingers apart to grab a pocket that was set for a different hand size, you reduce the effective depth of the hole and dramatically increase the risk of a controlled fall turning into a uncontrolled fall.

Train pocket strength separately from general finger strength using hangboard protocols that specify two-finger pocket positions. The load management for pockets is different from flat edge loading, and your fingers need specific adaptation to handle the lateral forces involved.

Pinch Holds: Raw Strength Meets Technical Precision

Pinch grips involve holding a feature between your thumb and fingers with the palm facing away from the wall. The load is transmitted through compression between your thumb pad and your finger pads, and the effectiveness of the grip depends on how much surface area you have in contact and how your wrist is positioned to stabilize the force.

Indoor climbing pinch holds are often set as vertical or outward-facing features that punish climbers who pull with their arms rather than their body position. The secret to efficient pinching is not crushing force. It is optimal geometry. A strong pinch comes from your thumb and fingers meeting at a point that allows your wrist to stay neutral or slightly extended, which places your forearm muscles in a more favorable position to generate force.

Wrist position matters more on pinch holds than almost any other grip type. A dropped wrist while pinching reduces the mechanical advantage of your thumb and forces your finger flexors to work harder for the same result. Rotate your wrist to find the angle where the hold feels most stable before you commit your weight.

Training pinch grip capacity requires specific tools. Campus boards with pinch rungs, pinch blocks, and dedicated pinch training sessions should be part of your program if you climb at a level where pinch holds are present in your projecting range. General climbing will not build pinch-specific strength the way it builds general pulling power.

Gastons, Underclings, and the Holds That Separate Climbers Who Send from Climbers Who Pump

Gastons are holds where you drive your thumb down and your fingers up, creating a prying force that would look like a horizontal upward motion if you watched it from below. They are named after French climber Gaston Rebuffat, who popularized their use in traditional climbing. The biomechanical challenge of a gaston is that your arm is in a pressing position rather than a pulling position, which recruits different muscle groups than you might expect.

Underclings are holds grabbed with the palm facing upward and pulled downward, using your body weight to generate the force rather than your arm strength. The shoulder must be positioned to allow the motion without impingement, and the wrist must be neutral enough to transmit force without straining. Underclings are often used on routes where you are sideways to the wall and need to generate lateral movement without barndooring off the feature.

Both gastons and underclings are grip types that punish lazy body position. When you grab a gaston without rotating your shoulder into the right position, you are loading the wrong tissues. When you undercling without getting your hips close to the wall, you are using twice the arm strength you need. These holds are technical in a way that jugs and crimps are not, and they reward climbers who think about their bodies as kinematic chains rather than collections of independent parts.

Sidepulls, footbeta, and heel-toe cambers all interact with gaston and undercling mechanics in ways that make the whole greater than the sum of the parts. The best technical climbers see these holds not as isolated features but as parts of a movement sequence where each hand position sets up the next.

Putting It Together: How to Train Every Grip Type Without Destroying Your Fingers

The reason most climbers plateau is not that they lack one specific grip type strength. It is that they have drilled their strengths and avoided their weaknesses until the avoidance became a ceiling. If you never train slopers, you will fall off slopers. If you never train pockets, a pocket sequence will be the end of your flash attempt. If you never train pinches, your sending grade on routes with heavy pinch requirements will top out below your potential.

A complete grip training program includes dedicated sessions for open-hand crimp capacity, two-finger pocket capacity, pinch strength, and sloper friction. These sessions do not need to be long. A 20-minute focused block on one grip type per week is enough to maintain adaptation, and a 30-minute block with progressive load is enough to develop new capacity if you are patient and consistent.

The non-negotiable rule is that you never train a grip type when you are fatigued from a climbing session. Grip training under fatigue leads to sloppy form, which leads to technique consolidation of bad habits, which is the opposite of what you are trying to accomplish. Morning grip training and evening climbing sessions is the ideal setup. If you must train the same day, train before you climb, not after.

Your fingers are the only interface between your body and the wall that you cannot replace. Treat them accordingly. Load them progressively, respect the adaptation timeline your tendons require, and never confuse pain with gain when it comes to pulley health.

The climbers who send their hardest projects are not the ones with the strongest fingers. They are the ones who know exactly how to use what they have. Learn every grip type. Learn when to use each one. Your next project is waiting.
