Hangboard Repeaters: The Complete Protocol Guide

What Are Hangboard Repeaters?

Repeaters are a hangboard protocol built around short, repeated hangs with very brief rests. Instead of one long hang or one maximal effort, you cycle through a series of hangs that mimic the grip and release pattern of actual climbing.

Think about what happens during a hard redpoint crux. You grab a hold, squeeze, move, release, catch the next hold. Your fingers never fully rest, but they get tiny windows of relief between moves. Repeaters train exactly this quality.

The classic format is the 7/3 repeater: 7 seconds hanging, 3 seconds off, repeated for 6 cycles. That adds up to one full minute of work per set, with 42 seconds of actual time under tension. Mark and Mike Anderson popularized this protocol in The Rock Climber's Training Manual, and their 2015 research paper reported strength gains as high as 21.5% after a 4-week cycle and 32% after a full eight-week training block. Those are serious numbers.

Tom Randall and the team at Lattice Training have built on this foundation, using repeaters across a wide spectrum of intensities. In their framework, the 7/3 format serves everything from pure endurance work (at lower loads with longer sets) to strength endurance training (at higher loads with shorter sets). The protocol is versatile enough to fit almost any climbing goal.

Why Repeaters Work

Repeaters sit in a unique training zone. They are not pure max strength work and they are not pure endurance work. Instead, they target strength endurance and power endurance, which is exactly what you need for sustained hard climbing.

Here is what happens during a repeater set:

Recruitment under fatigue. Your nervous system learns to fire motor units even as metabolic byproducts build up. This is the same demand you face on a sustained crux.

Hypertrophy stimulus. The total time under tension across a full session creates meaningful volume for forearm muscle growth.

Capillary and metabolic adaptation. The restricted rest periods force your local blood supply and energy systems to improve, helping you recover between moves on the wall.

The result is fingers that can produce force repeatedly without shutting down. That is finger strength applied to real rock.

The Standard Repeater Protocol

The Classic 7/3 Format

This is the backbone of repeater training. Every number in the protocol serves a purpose.

One set looks like this:

1. Hang for 7 seconds
2. Rest for 3 seconds (release the edge completely, shake your hand)
3. Repeat for 6 cycles
4. Total set duration: 1 minute (42 seconds hanging, 18 seconds rest)

That is one set on one grip position. A full session involves multiple sets across multiple grip positions.

The Anderson Brothers' version uses added weight on comfortable edges to keep intensity in the right zone. Lattice Training uses the same 7/3 timing but categorizes intensity ranges by training goal: 30-45% of max for endurance, 50-70% for strength endurance, and 75-90% for strength and hypertrophy.

For most climbers, the 50-70% intensity range is the sweet spot to start with.

Protocol Variations

The 7/3 is the standard, but other timing intervals work too. Tom Randall of Lattice Training has noted that both 7/3 and 5/2 repeaters replicate the contraction and relaxation cycles you encounter while climbing.

For most climbers starting out, the classic 7/3 with 6 reps is the right call. Modify the format only after you have run the standard protocol for at least one full training cycle and understand how your body responds.

Grip Positions for Repeaters

Training multiple grip positions builds well-rounded finger strength. Here are the grips you should know and how to use them in your repeater sessions.

Half Crimp (Recommended Default)

Fingers curled over the edge with the DIP joints (fingertip joints) flexed inward. The thumb rests alongside the fingers and is not engaged or locked over anything. This is the key distinction: no thumb lock. Half crimp is the recommended default training grip because it balances force production with manageable tendon loading. For a full breakdown of all grip positions, see our grip types guide.

Open Hand

Fingers extended and draped over the edge with minimal curl. You can use three or four fingers. The hand is relatively relaxed compared to a crimp. No thumb involvement. Open hand places the lowest stress on tendons and is a great training grip for building a strong base. The "three-finger drag" (index, middle, and ring fingers) is one popular variant of open hand, but open hand is not limited to three fingers.

Full Crimp

Same finger position as half crimp, but the thumb locks over the top of the index finger. This produces the most force but also creates the highest tendon load. Every climber uses full crimp on the wall regularly. For training, half crimp is a great default starting point, and you can add full crimp to your sessions as you get comfortable on the board.

Session Grip Selection

Start with half crimp and open hand as your core grips. These two positions cover most of what you will encounter on the wall. As you gain experience, add full crimp, pockets, or other positions based on your project demands.

A typical session might look like:

1. Half crimp (20mm edge)
2. Open hand, four fingers (20mm edge)
3. Three-finger drag (20-25mm edge)

As you develop, expand to 4-6 grip positions per session.

Equipment You Need

Repeaters are simple to set up. Here is what you need:

A quality hangboard. A board with multiple edge depths lets you progress through sizes as you get stronger. The Hangboard is built from beech wood for comfortable, skin-friendly contact during high-volume sessions like repeaters, where you are spending serious time on the edge.

Chalk. Keep it within arm's reach. You will be chalking up between sets and sometimes between reps. A chalk bag or chalk bowl next to your board works well.

A timer. A phone with a repeater timer app, a wall clock with a second hand, or a dedicated interval timer. The 7/3 timing is strict, so you need something reliable.

A pulley system or resistance band (for load management). Most climbers, especially when starting out, need to subtract weight to hit the right intensity range. A pulley with a counterweight is the standard tool. If your bodyweight is already the right load, you can skip this.

A weight belt or harness (for adding load). Once you are strong enough that bodyweight is too easy, you will need a way to add weight. An old climbing harness with plates clipped to the belay loop works perfectly.

A training log. Notebook, spreadsheet, or app. Write down your grip positions, edge depth, load, reps completed, and how each set felt. This is non-negotiable if you want to track progress.

Complete Session Structure

A good repeater guide gives you more than just the protocol. Here is what a complete session looks like from warm-up to cool-down.

Warm-Up (10-15 Minutes)

A proper warm-up sets the tone for the whole session and helps your fingers perform at their best.

Warm-up sequence:

1. 5 minutes of light movement. Arm circles, pull-ups on jugs, shoulder activation, or easy traversing if you have a wall. Get your heart rate up and blood flowing into your upper body.

2. Progressive hangboard hangs (5-10 minutes): Hang on your largest edge at bodyweight for 10 seconds. Rest 30 seconds. Repeat twice. Move to your working edge. Hang at bodyweight or lighter for 7 seconds. Rest 30 seconds. Repeat twice. Do one easy set of repeaters at a very light load (roughly 30-40% of max) to prime the movement pattern.

Your forearms should feel warm and ready. Not fatigued.

Working Sets

Once warm, move into your working sets. Here is an example session for a climber running three grip positions at two sets each:

During your sets:

Hang with control. No kipping, swinging, or bouncing. Keep your shoulders engaged, pulling slightly down and back. Do not hang passively from your joints. Breathe steadily. Holding your breath through a 7-second hang is counterproductive. If you cannot complete the full 7 seconds on a rep, reduce the load for the next set.

Cool-Down

After your final working set:

Forearm and finger stretches (2-3 minutes). Gently extend your wrists and fingers. Reverse wrist curls with a light dumbbell or resistance band (2 sets of 15) for antagonist balance. Gentle finger extensions with a rubber band (2 sets of 15).

Choosing Your Edge Depth and Load

Getting your load and edge depth dialed is essential. Too heavy and you will not complete the sets. Too light and you will not get the training stimulus you need.

Finding Your Max Hang

Before your first repeater cycle, establish a baseline. Here is a simple test:

1. Warm up thoroughly.
2. Pick your primary edge (20mm is standard for most boards).
3. Hang in a half crimp for 7 seconds at bodyweight. Rest 3 minutes.
4. Add 5-10 lbs. Hang for 7 seconds. Rest 3 minutes.
5. Continue adding weight until you can barely complete 7 seconds with solid form.
6. That maximum load is your 7-second max hang value (MVC-7).

Lattice Training recommends dedicating a separate testing session for this, not combining it with a training day.

Calculating Your Repeater Load

Your repeater load is a percentage of your total max hang load (bodyweight plus any added weight).

Most climbers should start in the 50-60% range. You can always bump it up next session.

Edge Depth Guidelines

When in doubt, go bigger. The load you hang with matters more than the edge size for repeaters.

Progression: When and How to Make It Harder

Your body adapts. That is the point. But smart, tracked progression beats random jumps in difficulty every time.

When to Progress

You are ready to increase difficulty when:

You have completed all prescribed sets and reps for two consecutive sessions at the current load. Your RPE on the final set is 7 or below (too much in reserve). You feel recovered and ready going into each session.

If those boxes are not checked, hold steady. There is nothing wrong with repeating the same load for several weeks. Consistency beats aggression.

Three Ways to Progress

The Anderson Brothers and Lattice Training both emphasize progressive overload, but they offer slightly different levers to pull.

Lattice Training particularly favors increasing set duration for endurance-focused repeaters. For example, progressing from two 4-minute sets at 40% intensity to two 5-minute sets over the course of an 8-week cycle.

The golden rule: change one variable at a time. Do not drop edge size and add weight in the same session.

Sample 4-Week Progression (Strength Endurance Focus)

Here is a conservative progression for half crimp on a 20mm edge:

After the deload, reassess and begin the next cycle. Run 2-3 full cycles before considering a major change like reducing edge depth.

Repeaters vs. Max Hangs

These are the two dominant hangboard protocols, and they train different qualities. Understanding the difference helps you pick the right tool for what you need right now.

When to Use Repeaters

You are training for routes with sustained difficulty. Your projects have long crux sequences (10+ moves). You feel strong on individual holds but pump out before clipping chains. You want to build a base of finger work capacity.

When to Use Max Hangs

You need to hold smaller or worse holds than you currently can. Your projects have one or two crux moves at your limit. You want to increase raw maximum finger force. You are in a dedicated strength phase.

Combining Both

Many experienced climbers alternate between repeaters and max hangs across training phases. A common approach from Lattice Training is running repeaters during a strength endurance or base-building phase and switching to max hangs (like the Eva Lopez protocol) during a strength or peaking phase. You do not have to choose one forever. Use the protocol that matches your current training goal. Our max hangs vs repeaters guide breaks down when to use each.

Listen to Your Body

Repeaters are a straightforward and well-tested protocol, but like any training, they work best when you pay attention to how your body responds.

Warming up matters. Taking 10-15 minutes to get your fingers and forearms ready before loading up makes a real difference in session quality and how your tendons feel the next day. Do not skip it, even when you are short on time. A few progressive hangs on larger edges are the minimum.

If you feel a sharp, sudden pain in a finger or tendon during a hang, stop the set. That is your signal to back off. There is a difference between the burn of a hard set (normal, expected, even welcome) and a sharp or unusual pain that was not there before. The burn means you are working. A sharp pain means something needs attention. Give it rest, and if it persists, get it looked at before training again.

Space your sessions out. Two repeater sessions per week with at least 48 hours between them gives your tendons and muscles time to recover and adapt. Every 3-4 weeks, take a full deload week with no hangboarding and only light climbing. This rest period is when your body consolidates the gains you have been building. Skipping it tends to stall progress or lead to nagging issues that slow you down. Be patient, train consistently, and let the process work.

Common Mistakes and How to Fix Them

1. Starting too heavy

This is the most common mistake by far. If your first session feels comfortable, that is a good sign, not a problem. Starting lighter and building up gets better long-term results than going heavy on day one. Aim for 50-55% of max for your first cycle.

2. Only training one grip position

If you only train half crimp, you develop a blind spot in open hand strength (and vice versa). Include at least two grip positions per session, ideally three or more. Half crimp and open hand together cover a lot of ground.

3. Sloppy rest timing

The 3-second rest is a feature, not a nuisance. If you are casually resting for 5-8 seconds between reps, you are running a different (and less effective) protocol. Use a timer and keep the rest periods strict.

4. No tracking or logging

If you are not writing down your loads, reps, and RPE, you are exercising instead of training. A hangboard app or timer can help you keep everything consistent. Check out our tips and mistakes guide for more on this. Repeaters work through progressive overload over time, and you cannot manage what you do not measure.

5. Training repeaters after a hard climbing session

Repeaters work best as a standalone workout or at least at the start of a session when you are fresh. Doing them after hard bouldering means your fingers are already fatigued and you will not get an accurate picture of your capacity. Dedicate specific days to hangboard training.

6. Skipping deload weeks

Every 3-4 weeks, take a full week off the hangboard. Light climbing is fine. This is when your body consolidates strength gains. Skip it and progress tends to flatten out.

7. Changing too many variables at once

Add weight OR drop edge size OR increase set duration. Not two of those at the same time. One variable per cycle keeps your training clean and your progress trackable.

Frequently Asked Questions

Start Training Repeaters

You have everything you need to run a real repeater protocol. Here is your quick-start checklist:

Test your max hang on your working edge (or estimate conservatively). Calculate your starting load (50-55% of max for your first cycle). Set up your training log (notebook, spreadsheet, or app). Chalk up and run your first session. Train 2x per week for 3 weeks, then take a deload week. Reassess, bump the load slightly, and begin the next cycle.

All you need is a solid hangboard mounted properly, chalk, a timer, and a way to manage load. Our best hangboards guide compares the top options. The Hangboard gives you multiple edge depths on one board so you can progress from larger to smaller edges as you get stronger, all on a surface that is comfortable enough for the kind of volume repeaters demand.

The hard part is not the protocol. It is showing up consistently, training at the right intensity, and being patient enough to let the gains compound over weeks and months. The Anderson Brothers and Lattice Training both emphasize the same thing: consistency and progressive overload over time beat any shortcut. Stick with it, track your numbers, and your projects will thank you.
