Strength training in climbing (12 controlled studies): positive effects on climbing performance, grip strength, upper-limb strength-endurance, max strength and power
Best trend is semi-specific, static + dynamic mixed, max-strength combined with hypertrophy or endurance work
Key Findings
Searches of MEDLINE, SPORTDiscus, ProQuest and Google Scholar for controlled pre/post training studies with detailed parameters; 12 studies included, classified by method (maximum strength MS, hypertrophy HYP, endurance END), specificity (specific / semi-specific / unspecific) and static vs dynamic exercise.
Results: (a) positive effects of strength training on all dependent variables — climbing performance, maximum grip strength, upper-limb strength-endurance, maximum upper-limb strength, upper-limb power; (b) a trend toward a mixture of MS with HYP or END training; (c) a trend toward semi-specific exercise; (d) similar effects for dynamic and static exercise, with a trend toward mixing both.
Recommendation: combine static and dynamic semi-specific exercises in a HYP+MS or END programme.
Not from this paper — Levernier & Laffaye 2019 (DOI 10.1519/JSC.0000000000002230, checked against its abstract): 14 elite/world-ranking boulderers; a 4-week finger-grip programme (small-hold suspensions, 2×/wk) raised slope-crimp maximal force +8% and RFD in the first 200 ms by 27.5–32% vs climbing-only controls.
Not from this paper — Medernach 2015 (DOI 10.1519/JSC.0000000000000873, checked against its abstract): 23 advanced boulderers; 4 weeks of fingerboarding raised grip strength (+2.5 kg), dead-hang (+5.4–6.7 s) and intermittent finger-hang (+26 s) more than bouldering alone.
Not from this paper — López-Rivera 2019 (DOI 10.2478/hukin-2018-0057, checked against its abstract): 26 advanced sport climbers, three 8-week dead-hang programmes; grip endurance +45% (ES 1) with intermittent dead-hangs, +34% (ES 0.6) with maximal added-weight hangs, only +7% (ES 0.1) with the combination — intermittent hangs were most effective; the two methods could be alternated over longer periods.
Practical Application
Across 12 controlled studies, strength training improved every climbing outcome measured, and the best-supported pattern was semi-specific work mixing static and dynamic exercise with max-strength plus hypertrophy or endurance training — so fingerboard/hangboard work belongs in a climber's programme, alongside, not instead of, semi-specific dynamic strength.
Not from this paper; the base's own practice: introduce fingerboarding only after a base of on-wall climbing plus tendon/pulley conditioning — never a beginner's first strength stimulus.
Not from this paper; the base's own practice: 2 short, fully rested sessions/wk; max-strength via short dead-hangs on an edge you can just hold, few reps, long rests; progress by small increments (shallower edge or a little added weight) only when the current load is controlled; stop at sharp finger pain or a "pop"; keep blocks short and reassess. The included studies used 4- and 8-week blocks at 2 sessions/wk.
Match method to goal: max strength/RFD (bouldering) → min-edge/added-weight max hangs (Levernier); strength-endurance (lead) → intermittent dead-hangs / repeaters (López-Rivera).
Limitations
Not from this paper (injury caveat, from the climbing-injury literature, REF-613): high finger loading (esp. crimp) puts large forces on the A2/A4 flexor pulleys — aggressive hangboard/campus progression is a common cause of finger injury; progress conservatively.
Not from this paper (youth caveat, REF-613): in adolescents with open growth plates, crimping/hangboarding/campusing can cause finger epiphyseal injuries — heavy fingerboard/campus training is contraindicated during the pubertal growth spurt.
SR base small/heterogeneous (12 studies, ES for 9); several studies use elite subjects → absolute dose may not transfer to recreational climbers; numeric prescriptions above are practitioner-standard, not one trial's protocol.

Title/lead rewritten to the review's actual findings (positive effects on all five outcomes; trends toward MS+HYP/END, semi-specific, static+dynamic mix); the injury/youth caveats moved out of the title and labelled as not from this review.
House dosing (≥1–2 yr base, 7–10 s hangs, 3–5 reps, ~4 wk blocks) labelled "the base's own practice" with the specific numbers removed; included-study figures (4 wk, 8 wk, 2×/wk, +8%, +27.5–32% RFD, +2.5 kg, +34/45/7%) attributed to their papers.
"López-Rivera: all programs improved grip endurance" -> the combination group gained only 7% (ES 0.1); intermittent hangs were most effective. Level A -> A-; Tier "mixed" -> Tier 2-5.
