Climbers treat max hangs and repeaters as two versions of the same thing. They are not.
They train different systems, adapt through different mechanisms, and solve different problems.

Almost every training mistake in finger strength comes from mixing these up.

1. Max Hangs: Training Maximal Force Production

Max hangs target the system that determines your force ceiling.
This system is neural: how many motor units you can activate, how fast they fire, and how efficiently force transfers through the tendons.

What max hangs actually train

• motor-unit recruitment
• rate coding
• tendon stiffness
• peak force at specific joint angles
• high-threshold motor learning

Why the loads must be high

If intensity is too low, the highest-threshold motor units do not activate.
You cannot train a system that never switches on.

Max hangs require:

• 80–100% intensity
• short duration (3–10 seconds)
• long rest (2–5 minutes)
• low total volume

They are strength training, not conditioning.

What improves

• force on small holds
• lock-off confidence
• power potential
• injury resistance (through higher tissue tolerance)
• warm-up effect for recruitment

What max hangs do NOT improve

• endurance
• capacity
• pump resistance
• ability to repeat force output

If you feel “fit” from max hangs, it’s psychological — not physiological.

2. Repeaters: Training Capacity, Not Strength

Repeaters are medium-intensity efforts repeated with short rests.
They do not activate high-threshold motor units enough to drive maximal strength adaptation.

What repeaters actually train

• metabolic efficiency
• local circulation
• ability to maintain force under fatigue
• clearance of metabolic byproducts
• capillarisation
• recruitment maintenance (keeping moderate firing patterns under fatigue)

Why repeaters can feel harder but make you no stronger

Fatigue ≠ strength stimulus.
Repeaters burn because they build metabolic stress — not neural drive.

Intensity is too low and too sustained to improve max strength.
But they strongly develop:

• power-endurance
• finger density
• tolerance to longer sequences
• resistance against form breakdown
• the ability to keep climbing when tired

Repeaters are conditioning, not strength.

3. Why people confuse the two

Reason 1 — They both “feel hard”

Max hangs feel hard because the load is high.
Repeaters feel hard because the metabolic stress is high.
Different systems, identical subjective difficulty.

Reason 2 — Both use a hangboard

Same tool, different purpose. This leads many climbers to treat “hangs” as one-dimensional.

Reason 3 — Repeaters give a fast sensation of progress

Repeaters improve quickly because metabolic adaptations are fast.
Max strength improves slower because (real) strength is slower to adapt.

This misleads climbers into thinking repeaters are sufficient for strength.
They aren’t.

4. How to decide which one you need

If your problem is force → train max hangs

Indicators:

• you fall off small edges even when fresh
• you feel “weak” regardless of pump
• moves feel impossible rather than tiring
• you need more power in boulders
• your warm-up massively changes your performance

If your problem is repeated effort → train repeaters

Indicators:

• you can do the moves but can’t link them
• you get forearm burn early in the session
• you fade after 5–15 moves
• you struggle to maintain form on circuits
• your fingers collapse when fatigued

Most climbers need both, but not simultaneously and not in equal proportions.

5. You cannot combine both in one session

Trying to train both systems at once reduces the effect of each:

• Max hangs require freshness and high recruitment.
• Repeaters require fatigue and volume.

If you place repeaters first, recruitment drops and max hangs become useless.
If you place max hangs first, repeaters become harder but train less capacity.

Result: both stimuli become watered-down and ineffective.

The rule is simple:

One system per session.

6. Summary: What They Really Train

Knowing this distinction prevents wasted training time and explains nearly every plateau related to finger strength.
