New study tests whether strengthening finger extensors boosts climbing performance

This study looks at whether adding finger extensor training (strengthening the muscles that open your hand) to the usual flexor training (grip-strengthening exercises) improves climbing performance. About 36 healthy adult climbers will follow either a traditional flexor-only training plan or a combined flexor-plus-extensor plan for six weeks. Researchers will measure grip strength, finger endurance, and self-reported arm and hand function to see which approach works better.
