Increasing load is where most climbers injure themselves.
Not because they add weight — but because they add it too fast, too inconsistently, or at the wrong moment.
This article gives you the exact rules for safe intensity progression, so you know:
- when to increase
- how much to increase
- when NOT to increase
- what signals matter
- what a correct progression feels like
No guesswork. No ego. Just structure.
1. The only safe way to increase load
Progression must follow this sequence:
STEP 1 — Repeatability
Your reps must be stable first.
STEP 2 — Volume tolerance
You must repeat the same total work across sessions.
STEP 3 — Intensity increase
Only now do you add load — and only a tiny amount.
If the order is reversed, your tendon gets hit with unstable forces, unstable angles, and unstable fatigue → unsafe.
Most injuries happen because climbers skip step 1.
2. How much load can you safely add?
Tiny increases do the work.
Big increases do the damage.
Safe increases:
➡️ +2% to +5% of current load
(For most climbers: +0.5 kg to +2 kg.)
Unsafe increases:
✖ +5% to +10%
✖ “I’ll just add one more plate”
✖ jumps larger than 2 kg
✖ adding load before stabilizing volume
The tendon adapts to consistency, not jumps.
3. How to know you’re ready to increase load
A climber is ready for progression when three things are true:
✔ 1. Sessions feel similar
Rep 1 → consistent
Rep 2 → predictable
Rep 3 → mild fatigue, no collapse
✔ 2. No angle drift in PIP/DIP
If the middle knuckle or fingertip joint collapse/unroll → NOT ready.
✔ 3. Next-day feel is normal
A slight tightness is fine.
Sharpness, swelling, or stiffness → NOT ready.
If all three are met → increase intensity.
If one fails → hold load until stable.
4. The safest spacing for intensity increases
Never increase intensity two sessions in a row.
Use this rule:
Small increase → hold for 2 sessions
Larger increase (3–5%) → hold for 3–4 sessions
This allows:
- collagen remodeling
- joint angle stabilization
- force consistency
- predictable fatigue patterns
Most climbers increase too early, not too late.
5. The two progression mistakes that ruin blocks
❌ Mistake 1 — Increasing load because “it felt easy today”
You judge readiness based on session freshness, not tendon adaptation.
Fresh nervous system ≠ remodeled tendon
Good mood ≠ safe progression
One strong rep ≠ stable structure
❌ Mistake 2 — Increasing load during inconsistent weeks
Stress, sleep, travel, finger coldness — all influence force expression.
If your performance is chaotic:
Do not progress
Do not deload
Just hold
Consistency is king.
6. What safe progression feels like (very concrete)
Before increasing:
- hangs feel “smooth”
- small fatigue, controlled
- equal reps across sessions
- no surprise pains
- angles stable
After increasing:
- slightly heavier first rep
- fatigue arrives a bit sooner
- angle stability still intact
- rep 3 is “work” but predictable
- next day feels normal
If progression feels exciting → too big
If progression feels boring → perfect
7. What unsafe progression feels like (even more concrete)
If you feel any of this after adding weight:
- sharp fatigue
- sudden DIP unrolling
- middle knuckle collapsing
- shaking that didn’t happen before
- rep 2 much worse than rep 1
- angle instability
- next-day tightness in 1 spot
→ rollback intensity immediately.
Tendons don’t send subtle signals.
8. When you should stop progressing
Progression stops temporarily when:
- reps become inconsistent
- angles drift
- you feel sharpness
- life-stress increases
- technique worsens
- sessions vary too much
- cold weather affects hands
HOLDING THE LOAD for a few sessions is not failure —
it's tendon adaptation.
Progression only matters long-term.
Failing to overload the tendon safely matters long-term.
Micro-pauses do not.
Putting it all together
Safe intensity progression follows a simple structure:
-
stabilize reps
-
stabilize angles
-
stabilize volume
-
increase load by 2–5%
-
hold the load multiple sessions
-
only progress when consistency is high
Progress happens when you respect these boundaries.
Injuries happen when you ignore them.
This is how you build tendon strength, not tendon stress.
