You know your climbing training is working when something you measured before the block has moved when you measure it again the same way. Not when you feel stronger, and not only when your max grade goes up, because that’s the last thing to change. A retest is a short, repeatable check you run every four to six weeks so you can answer “is this working?” with evidence instead of mood.
Most climbers never retest, so they judge a training block on how the last session felt. That’s how good plans get abandoned and bad ones get kept.
Why “I feel stronger” is a bad test
How a session feels tracks how rested you are, how your skin is, how busy work was and whether the setters were kind this week. All of that swings far more from day to day than your actual ability does over a month. A week of good sleep can feel like a breakthrough; a hard week in the middle of a block can feel like going backwards when you’re simply tired.
Your max grade is honest, but slow. Climbers usually improve in jumps: weeks at one grade, then several problems going close together. If max grade is your only measure, you can spend two good training blocks believing nothing is happening, then quit just before the jump.
The fix is to measure the things that move first, and to measure them the same way every time.
What to measure: the signals that move first
Pick a handful of these, not all of them. Three well-chosen signals beat ten you track carelessly.
| Signal | What it tells you | How to measure it | Who it’s for |
|---|---|---|---|
| Benchmark problems | Whether hard moves you couldn’t do now go | Three unsent problems at your limit, in different styles. Note which moves go | Everyone |
| Attempts to send | Whether hard problems take less work | Count attempts on problems at your max grade | Everyone |
| Flash grade | Whether your reading and movement are improving | Highest grade you do first try, across a session of fresh problems | Everyone |
| Styles at your max grade | Whether you’re closing gaps or just repeating strengths | Count different styles (crimpy, slopey, steep, slab, dynamic) ticked at your max | Everyone |
| Easy-climbing volume | Whether your work capacity is rising | Problems two grades under your max climbed in a fixed time before your form slips | Everyone |
| Finger test on a fixed edge | Whether finger strength is changing | Same edge, same grip, same added weight or time | Climbers past their first year who already hangboard |
Benchmark problems are the backbone. They’re specific to you, they test the thing you actually care about, and a move going that wouldn’t go last month is about the clearest progress signal climbing offers. The catch is that gym problems get reset, so choose benchmarks that will still be up in six weeks (ask the setters, or use a board such as a Moonboard or Kilter if your gym has one), and keep a backup list.
How to run a retest you can trust
A retest is only worth something if the conditions match. Otherwise you’re measuring your week, not your training.
Match the conditions
- Be fresh. Retest after a rest day or two, not at the end of a hard week. Physiotherapist Alberto Regola’s guide to testing for climbers suggests no training for 48 hours before strength tests.
- Same warm-up. Write yours down and repeat it exactly. The same guide uses about 15 minutes of general warm-up followed by 10 minutes specific to the test.
- Same order. If you tried benchmark A first last time, try it first again. Fatigue from earlier efforts changes later ones.
- Same rest. Use a timer between attempts: three minutes or more for limit problems.
- Note what you can’t control. Temperature and humidity change friction, and friction changes results. A cold, dry autumn evening and a muggy summer one aren’t a fair comparison, so write the conditions down and allow for them.
The wall retest (any climber)
This takes one session, and replaces your limit session that week.
- Your usual warm-up, written down and unchanged.
- Benchmark problems in the same order as last time: up to four attempts each, three to five minutes between them. Record which moves went and the highest point reached.
- Flash attempts on three or four fresh problems at the grade you think is your flash level. Record which went first try.
- Stop while attempts are still good quality. A retest isn’t a training session, and you don’t need to finish wrecked.
Then fill in the line for this block: benchmarks (moves done, sends), flash grade, how you felt, conditions.
The finger test (only if you already hangboard)
If you’re past your first year and already training on a hangboard, a finger test adds a cleaner number. Tendons and pulleys adapt more slowly than muscle, which is why it isn’t for climbers in their first year: for them, climbing already loads the fingers enough, and the wall retest is the right tool.
Keep it simple and sub-maximal: one edge, one grip, one hang time, with the added weight or assistance you used last time. Did it feel easier, or could you add a little? Don’t chase a true maximum on retest day, and stop immediately if anything in a finger hurts.
The research on this is encouraging if you’re consistent. A 2025 systematic review of finger-strength test reliability, covering 15 studies and 747 participants, found that maximal finger-strength tests generally give very consistent results when repeated, and that fixed edges of roughly 20–23 mm with a standardised grip were the most reliable. The same review notes that room temperature, humidity and how chalk is used can change results, and that self-selected grips added variability. Same edge, same grip, same conditions: that’s what makes the number mean anything.
When to retest
Retest at the end of a block, after the easier week, when you’re freshest. For most climbers that means every four to six weeks. That’s often enough to catch a plan that isn’t working before you’ve wasted a season on it, and long enough for something to change.
Don’t retest in the middle of a hard block. You’ll be carrying fatigue, the numbers will look flat or worse, and you’ll be tempted to change a plan that was doing its job. Fitness built in training usually shows once the fatigue clears, which is the point of the deload week in the four-week plateau block.
And don’t retest every week. Weekly checks mostly measure noise, and testing often turns training sessions into tests, which means less training.
Reading the result
Compare against your last retest, not against your best ever day or anyone else’s numbers.
| What you see | What it probably means | What to do |
|---|---|---|
| Benchmark moves went that didn’t before | The block worked | Keep the structure; pick slightly harder benchmarks |
| A benchmark sent | The block worked, clearly | Replace it with a new one in the same style |
| Flash grade up, benchmarks flat | Movement is improving; the limit gap is specific | Look at what the benchmarks have in common and train that |
| Nothing moved, felt fresh | The plan isn’t hitting your limiting factor | Change one thing: the style you train, or the type of session |
| Nothing moved, felt tired | You retested too soon or recovered too little | Take an easier week and retest again before changing the plan |
| Worse across the board | Usually fatigue, illness or a bad day | Rest, then retest; if it’s still worse, look at sleep, stress and session load |
The most useful row is “nothing moved, felt fresh”. One flat retest after a well-run block is a signal to change one variable, not everything. If you change your sessions, your frequency and your benchmarks all at once, the next retest can’t tell you which change mattered.
One good result isn’t proof either. A single benchmark going on a cold, dry evening could be the conditions. Two retests in a row showing the same direction is a trend you can act on.
Common retest mistakes
Changing the test. Swapping benchmarks because the old ones felt discouraging throws away the comparison. If a benchmark is reset, note it and replace it with one of a similar style and difficulty.
Testing tired. The commonest mistake, and the one that makes good training look useless.
Turning a bad retest into a max session. If the first benchmark goes badly, don’t throw extra attempts at everything to rescue the day. Finish the protocol, write it down and go home.
Only measuring strengths. If all three benchmarks are crimpy because you like crimps, the retest will tell you about crimping and nothing else. At least one benchmark should be in a style you avoid. The three gaps that cap climbers at V4 are a good place to look.
Expecting a grade a month. Over four to six weeks, one or two benchmark moves going is a good result. Honest timelines for reaching V5 explains why progress at the middle grades comes in jumps rather than a steady line.
Make the retest part of the plan
A retest only works if it’s on the calendar before the block starts. Choose your benchmarks now, write down your warm-up, and put the retest session at the end of week four, five or six. If you’re working on fingers without a board, the gym-wall finger plan gives you climbs that make good benchmarks for that too.
If you’d rather not keep the spreadsheet yourself, Mantle plans your training week by week from what you log and builds the retests into each block, so you can see whether it’s working rather than guessing.
