Finger Training for Climbing

Why train finger strength?

Because it is the dominant physical factor in climbing ability. In a 2025 study of 307 climbers, maximal finger strength accounted for about two thirds of the variance in climbing ability that the tests explained: 68% in men and 64% in women.

That does not prove training it makes you climb harder, but it makes finger strength the biggest lever for most climbers who already climb regularly. What predicts climbing grade compares it with endurance and speed of force.

How heavy should max hangs be?

Hard enough that you could hold about 3 more seconds. A max hang is about 10 seconds on an 18 to 20 mm edge in a half crimp, 3 to 5 hangs per session, 3 minutes of rest between hangs, twice a week with at least 48 hours between, for 4 to 8 weeks.

Training to failure and cutting the rests are the common mistakes. Add 1 to 2 kg when the last hang feels easy. The full protocol and the research behind it are in Max hangs.

Add weight or use a smaller edge?

Add weight on a medium edge first. Two studies point that way: in the 2012 study of nine elite climbers, starting with added weight on an 18 mm edge did better than starting with small edges (though with only nine climbers the difference was not statistically significant), and in a randomized trial of climbers new to the hangboard, the added-weight group improved grip strength more than climbing alone, while the smaller-edge group did not.

Added weight moves in small, measurable steps. Smaller edges make sense for specificity, when you have no weights, or for very light climbers. See Smaller edges or more weight?.

How long each hang should last is in How long to hang.

Do you have to hang with your feet off the floor?

No. In a no-hang you keep your feet on the floor and pull at about 40% of your maximum: twenty 10-second pulls over six grip positions, 20 seconds of rest, at least 6 hours from other workouts. In a 2024 study of 526 climbers, those who did only no-hangs gained 2.5% in strength-to-weight, max hangs alone 3.2% and both together 5.8%. The study was retrospective, and the no-hang-only result was not statistically different from climbing only.

Keeping your feet on the floor also lets you adjust the load as you go, which is what partial hangs rely on. Read the full story in No-hangs.

For a daily version, see Daily low-intensity hangs; for training one arm at a time, see One-arm hangs.

Is speed of force different from maximum strength?

Yes. Rate of force development is how quickly you reach high force, the steepness of the start of the curve. Elite climbers produced 74.9% higher RFD than advanced climbers, against 39.7% higher peak force. It responded to four weeks of hangs on small holds, twice a week.

Intent is the stimulus: short, maximal, fast pulls with full rest, on fresh fingers. Explosive loading is demanding on pulleys, so build a base first. See Rate of force development.

Should you train the finger extensors?

It is plausible and low-cost, not proven. Flexors were on average 6.3 times stronger than extensors in 78 experienced climbers, and the ratio grew with climbing level. Only dedicated, high-intensity extensor training raised extensor strength, but no study has linked the ratio to injury risk. Details in Finger extensor training.

What about monos?

Mono training is done one finger at a time, and gradually. The post suggests testing each finger, then training at 50% of the maximum strength of the two-finger pair, for a month, then a week off and a retest. The most common mono injury is a tear to the lumbricals. See Training for monos.

How do you know your load?

By measuring it. A weight belt tells you what you added, not how hard you pulled, and the right load changes with your day. Test your maximum first: How to test your finger strength.

Train it with Entralpi

Entralpi is a ground force plate: you stand on it, hang from your own hangboard, and the app shows the force your fingers hold, live. You can test your maximum, then train each hang or no-hang at a target percentage. The finger strength test measures each finger alone, and what each test measures explains the numbers.
