Climbing Rest Day Calculator
Calculate optimal rest days between climbing sessions based on intensity, volume, and finger load to prevent injury.
Recovery between climbing sessions is critical for tendon health and strength gains. Unlike muscles, which recover in 24–48 hours, finger tendons and pulleys need 48–96 hours depending on load intensity.
Recovery Formula: Base Rest Hours = Session Intensity Factor × Volume Multiplier × Finger Load Modifier
Intensity Factors:
| Session Type | Intensity Factor | Description |
|---|---|---|
| Easy (warm-up grade) | 12 | Well below max, low pump |
| Moderate (project grade -2) | 24 | Steady effort, moderate pump |
| Hard (project grade) | 36 | Near max effort, heavy pump |
| Max (limit bouldering) | 48 | Full-crimp, campus, max hangs |
Volume Multiplier: Based on total climbing time:
- Under 1 hour: ×0.8
- 1–2 hours: ×1.0
- 2–3 hours: ×1.3
- Over 3 hours: ×1.6
Finger Load Modifier:
- Mostly open-hand / slopers: ×0.8
- Mixed grips: ×1.0
- Mostly half-crimp: ×1.2
- Full-crimp heavy: ×1.5
Worked Example: Hard bouldering session, 2 hours, mostly half-crimp:
- Base = 36 × 1.0 × 1.2 = 43.2 hours → ~2 days rest
Moderate sport climbing, 2.5 hours, open-hand:
- Base = 24 × 1.3 × 0.8 = 24.96 hours → ~1 day rest
Additional Modifiers:
- Age 35+: add 25% more rest
- Age 45+: add 50% more rest
- If you feel tweaky or sore tendons: add 24 hours minimum
- Consecutive climbing days: each successive day adds 30% to base
Weekly Maximums by Level:
- Beginner: 2–3 sessions/week
- Intermediate: 3–4 sessions/week
- Advanced: 4–5 sessions/week (with periodization)
Rest does not mean inactivity. Light cardio, stretching, and antagonist exercises (push-ups, reverse wrist curls) are encouraged on rest days.
