Campus Board Training: When You're Ready and How to Start

The campus board has a reputation problem. Some climbers treat it as the shortcut to power. Others treat it as a finger-injury machine that should be avoided. Neither view is accurate. A campus board is a tool that delivers very high finger loads at very high speed. That makes it effective for the right climber at the right time, and a poor choice for everyone else.

This article covers what campus training actually trains, what the research shows, how to judge whether you are ready, and how to run your first sessions. For the broader picture of power itself, see Power: How Climbing Power Actually Works.

1. What a campus board trains

A campus board is a slightly overhanging board with evenly spaced wooden rungs. You move up, down or between rungs using only your hands, with your feet off the wall. The format was developed in the late 1980s by Wolfgang Güllich, who wanted a way to train the dynamic finger strength he needed for his hardest routes.

Mechanically, every campus move has three phases: a fast pull that moves your center of mass upward, a short flight with one hand free, and a catch, where the fingers must reach high force within a fraction of a second to stop the fall.

The catch is what makes campus training different from a hangboard. On a hangboard you build force slowly and hold it. On a campus board you must produce force fast, against a moving body. This is what climbers call contact strength, and in biomechanics it is closely related to rate of force development (RFD).

The same feature is what makes it risky. A dynamic catch produces a load spike that is higher than your body weight, and the fingers often land in a less controlled position than on a static hang. That spike is largely carried by the flexor tendons and the pulleys, especially the A2 pulley (see The A2 Pulley: Function, Stress Points & Why Climbers Injure It Most).

2. What the research shows

Campus training can improve climbing-specific power

The clearest study is a randomised controlled trial by Stien et al. (2021). Sixteen advanced to elite male lead climbers (minimum redpoint 7a+, no campus board use in the previous six months, but familiar with intense finger training) were split into three groups for five weeks:

  • campus board training twice a week (n = 6);
  • campus board training four times a week, with the same total volume (n = 5);
  • a control group that kept climbing as usual (n = 5).

Each session used four exercises of four sets each, on rungs of 25, 20 and 15 mm, with two to three minutes of rest between sets. All moves were done at maximal effort and speed.

When both training groups were combined, they improved more than the control group in bouldering performance, maximal reach on the campus board, moves to failure and isometric strength on a rung. The two-session group improved bouldering performance more than controls. The four-session group improved rate of force development more than controls. There were no significant differences between the two training groups, and no training injuries were reported.

The limits matter. The sample was very small, all participants were men, the climbers were already strong and experienced, and only the first session was supervised. The authors themselves name the low sample size as the main limitation. The study shows that five weeks of campus training can work for advanced climbers. It does not show that campus training is a good idea for intermediate climbers.

Injury data is mixed

Observational studies do not agree on whether campus training raises injury risk. A large survey by den Hengst et al. (2026) of 745 recreational climbers found that campus board use was associated with lower odds of finger, hand and wrist injury, while hangboard use was associated with higher odds. The authors point out that earlier studies found the opposite for campus training, and that a cross-sectional survey cannot show cause and effect. A plausible explanation is selection: climbers who use a campus board are often more experienced and better conditioned. The survey does not tell you that campusing protects your fingers.

Adolescents are a special case

For young climbers, the evidence and the expert guidance are clear. Growth plates in the fingers stay open until roughly age 17. Stress fractures of the growth plate at the middle finger joint are a recognised injury in adolescent climbers. In a case series by Schweizer et al. (2019), 16 patients with this injury had a mean age of 14, and 44% reported campus board training. That figure comes from a small group without a comparison group, so it cannot prove cause, but it fits the mechanism. The British Mountaineering Council, with guidance approved by the UIAA Medical Commission, advises that climbers under 18 should not campus feet-off or dynamically.

3. Are you ready? A practical checklist

No study has validated a readiness test for campus training. The criteria below are conservative coaching rules based on the mechanics above and on the profile of the climbers in the research. Treat them as a minimum, not a guarantee.

  • Age: 18 or older, in line with the BMC and UIAA guidance.
  • Training history: at least one to two years of structured finger training (hangboard or lifting) without recurring finger pain. Tendons and pulleys adapt more slowly than muscle, so strength alone is not enough (see How Tendons Really Adapt).
  • Climbing level: you regularly climb hard boulders or routes where dynamic moves on small holds are the actual problem. If you mainly fail on footwork, body position or pump, campus training targets the wrong thing.
  • Current injury status: no current finger, elbow or shoulder pain. A recent pulley injury is a clear reason to wait until a physio has cleared you for dynamic loading.
  • Measured strength: you know your current finger strength. Test it with a repeatable protocol such as the Finger Testing Protocol, or on a Max Climbing testing station in your gym, and compare it with the ranges in Finger Strength Benchmarks. If your static strength is clearly low for your grade, build that first. Power cannot exceed your strength ceiling.

If you miss one or more of these, you are not locked out of power training. Limit bouldering and steep board climbing with feet on also train contact strength, with far less peak load per move.

4. How to start: a graded progression

The safest way to begin is to reduce the load spike first and add speed and distance later. Each stage below should feel controlled for at least two to three weeks before moving on.

Stage 1: Feet-on campusing

Place your feet on a foothold or the bottom of the board and move your hands up the rungs. Your legs take part of your body weight, so the catch load is lower. Focus on landing the rung in a stable half crimp or open hand, without the fingers collapsing into a full crimp.

Stage 2: Feet-off ladders on large rungs

Hang from the bottom rung and climb hand over hand, one rung at a time (1-2-3-4). Use the largest rungs available. Stop the set the moment a catch feels sloppy.

Stage 3: Longer reaches

Once ladders are easy and controlled, skip rungs (1-3-5) or do single maximal reaches from a matched start. Distance increases the flight phase and the catch force, so add it slowly.

Stage 4: Smaller rungs and double moves

Smaller rungs and double dynos, where both hands leave and catch together, produce the highest loads. They belong only to climbers who have trained the earlier stages for months. The BMC guidance specifically advises against double dynos unless you are very experienced on the board.

5. Session structure

Campus training is power training, so it follows the same rules: high quality, low volume, full recovery. A starting template for a beginner on the board:

  • Placement: at the start of the session, after a full warm-up, never when you are tired.
  • Warm-up: 15–20 minutes of progressively harder climbing, then a few easy feet-on campus moves.
  • Volume: 4–6 sets of 3–6 hand moves. In the Stien study, experienced climbers did four exercises of four sets each; beginners should do less.
  • Rest: at least 2–3 minutes between sets, as in the research.
  • Frequency: one session a week to start, at most two. Leave at least 48 hours before the next hard finger session.
  • Block length: 4–6 weeks, followed by a period without campusing.

For how campus work fits next to max strength training without interfering with it, see How to Build Power Without Losing Strength.

6. How to tell if it is working

Power is harder to measure than static strength, but simple proxies are enough:

  • the furthest rung you can reach from a matched start, on the same rung size;
  • the number of controlled moves before your catches start to break down;
  • how often you stick specific dynamic moves on your benchmark boulders.

Test them fresh, in the same conditions. More options are in Measuring Power Without a Lab.

7. Common mistakes

  • Campusing while fatigued. Catch quality drops and the load spike lands on fingers that are already tired.
  • Catching in a full crimp. This raises pulley load. If you cannot land a rung in a stable half crimp or open hand, the rung is too small or the move is too long.
  • Ignoring warning signs. Pain at the base of a finger, pain during a catch or a popping sensation means you stop the session. Persistent pain needs a physio assessment before any further dynamic loading.

8. Equipment

Most climbing gyms have a campus board, and that is the best place to start. If you train at home, you need a slightly overhanging wall, evenly spaced rungs and a safe landing. Large-format wooden rungs such as the Workshop 19/50 Campus Rungs are a sensible choice for early stages, because larger rungs reduce peak finger load. The full range is in the Campus Board Accessories collection.

Putting it all together

  • Campus training targets contact strength: producing high finger force fast, during a catch.
  • One small randomised study in advanced male climbers found clear gains in bouldering performance and climbing-specific power after five weeks.
  • Injury data from surveys is mixed and cannot show cause and effect. Under-18s should not campus feet-off or dynamically.
  • Start feet-on, progress one variable at a time, keep volume low and train fresh.

Next step

Before you add a campus block, check whether power is really your limiter. Run the Find Your Limiter check and measure your current finger strength on a hangboard or a Max Climbing testing station. If your static strength is still low for your grade, a block of the Max Hangs Protocol will do more for you right now than a campus board.
