Hangboard Training Calculator
Plan your hangboard training progression with hang duration, rest intervals, and added weight progression. Calculate work-rest ratios and session volume for finger strength training.
About this calculator
This calculator builds a structured hangboard session around the classic repeaters protocol — 3 sets of 6 hangs — while scaling the actual hang duration to your own tested ability. Training Hang Duration is set at 70% of your Max Hang Time (the longest you can hold the target edge at body weight when fresh), a common intensity target that lets you accumulate enough total time under tension without failing partway through a set. Rest Between Hangs is calculated as three times the training hang duration (with a 30-second floor), reflecting the standard guidance that finger tendons need proportionally longer recovery than muscle between short, intense contractions; Rest Between Sets is fixed at 3 minutes. From there it computes Total Session Time (all hangs and rests summed) and Training Volume — total load (body weight plus any added weight) multiplied by hang duration and total hangs, in kg·seconds — as a rough measure of how much work the session represents, useful for comparing sessions or tracking overall load week to week.
For progression, it takes your Current and Target Added Weight and your chosen number of Weeks to Progress and divides the difference evenly, giving a Weekly Weight Increase for straightforward linear loading. Current and Target Relative Strength express added weight as a percentage of body weight, a common way climbers benchmark finger strength against themselves or others. Because tendon adaptation is slow, resist the urge to compress the timeline — if the weekly increase feels aggressive, extend the number of weeks rather than risk overuse injury.

How to Use This Calculator
- Enter your body weight in kg and the additional weight you will add (or subtract) with a harness weight belt.
- Select your current finger strength level and your training goal (strength, endurance, or max hang).
- Set the hang duration in seconds and number of sets you are targeting per session.
- Read the recommended Rest Between Hangs and Rest Between Sets to avoid overloading tendons.
- Follow the Weekly Weight Progression chart to add load gradually and reduce injury risk.
- Use Total Volume per Session to ensure your training load stays within safe limits for your experience level.
How the result changes with Target Added Weight
| Target Added Weight | Weekly Weight Increase | Training Hang Duration |
|---|---|---|
| 10 | 0.63 kg | 11 sec |
| 15 | 1.25 kg | 11 sec |
| 30 | 3.13 kg | 11 sec |
| 50 | 5.63 kg | 11 sec |
What each input means
- Max Hang Time
- Your maximum hang time on the target hold (e.g., 20mm edge) at body weight only. Test fresh after a warm-up.
- Body Weight
- Your body weight in kilograms. Used to calculate relative finger strength and training load.
- Current Added Weight
- Weight currently added via a harness or weight belt during hangs. Enter 0 if training at body weight only.
- Target Added Weight
- Your goal added weight for the training cycle. Typical progression is 1-2 kg per week for intermediate climbers.
- Weeks to Progress
- Number of weeks for your training cycle. 6-12 weeks is typical for a focused hangboard phase.
What each result means
- Weekly Weight Increase
- Amount of weight to add each week for linear progression to your target.
- Work : Rest Ratio
- Ratio of hang time to rest time within each set. Typical ratios are 0.15-0.35.
- Training Hang Duration
- Recommended hang duration per rep (70% of your max hang time).
- Rest Between Hangs
- Rest period between individual hangs within a set.
- Total Session Time
- Estimated total hangboard session duration including all sets and rest periods.
- Total Hangs per Session
- Total number of individual hangs across all sets (3 sets × 6 hangs).
- Training Volume
- Total training load: (body weight + added weight) × hang duration × total hangs.
- Current Relative Strength
- Current added weight as a percentage of body weight. Elite climbers hang 60-100%+ of body weight.
- Target Relative Strength
- Target added weight as a percentage of body weight.

Frequently Asked Questions
Why is Training Hang Duration only 70% of my Max Hang Time instead of the full value?
Max Hang Time is meant to represent the longest single hang you can hold at body weight when fresh, essentially a one-rep max. Training at that full duration on every rep in a multi-hang set would cause form breakdown and early failure, so the calculator scales it down to 70% — a common repeaters-protocol intensity that lets you complete all 6 hangs in a set under control while still accumulating meaningful time under tension.
How is Rest Between Hangs calculated, and why does it have a 30-second floor?
It's simply three times your Training Hang Duration, reflecting the guidance that finger tendons need proportionally more recovery than muscle does between short, high-intensity contractions. The 30-second floor keeps very short hang durations (say, a 3–5 second training hang) from producing an unrealistically brief rest period that wouldn't actually let your fingers recover between reps.
Why does Training Volume use my Current Added Weight instead of my Target?
Training Volume is meant to describe the load of the session you're about to do today, so it multiplies today's total load — body weight plus Current Added Weight — by Training Hang Duration and the fixed 18 total hangs per session (3 sets of 6). As your Current Added Weight climbs toward your target over the following weeks, recalculating with the updated current weight will show your session volume increasing along with it.
If I extend Weeks to Progress, why does the Weekly Weight Increase get smaller?
The calculator spreads the entire gap between your Current and Target Added Weight evenly across however many weeks you choose, so Weekly Weight Increase is just that difference divided by Weeks to Progress. Stretching the same total weight gain over more weeks produces smaller weekly jumps, which is exactly the intended lever if a shorter timeline's per-week increase looks too aggressive for tendon adaptation.
