What is it?
A climbing grip trainer is a small, handheld tool that provides light resistance when you squeeze it. At Bould Move, we stock grip trainers for climbing that are perfect for finger injury rehab, and building endurance for having better recovery between attempts and sessions. Check out this article from Friction Labs on the best hand grips for improving finger strength for more tips on grip training.
Explain its Purpose
Unlike hangboarding, board climbing or block lifts, the climbing grip trainer doesn’t provide enough resistance for maximal strength training. Instead, it’s a great tool for rehab and aerobic capacity training. It allows climbers to restore function after injury, maintain finger health, and build the base endurance needed for longer and more frequent sessions.
Why We Chose It
We chose to stock grip trainers because they provide a portable, skin friendly and safe way to rehab and utilize aerobic restoration and capillarity (ARC) training — you can use them at home, in the gym, or even at work.
How We Use It for Training
The grip trainer is especially useful for ARC-style training — low-intensity, high-volume work aimed at improving blood flow and recovery capacity.
Practical protocol:
- Volume: 10–20 minutes of light, continuous squeezes per session.
- Exercise choice: Squeeze-and-release with smooth rhythm.
- Repetitions: Aim for steady, unbroken cycles rather than reps.
- Rest: None — it’s about constant low effort.
- Timing: Best on rest days or before/after climbing as a conditioning tool or warm-up.
This helps build aerobic endurance in the forearms, reducing the “pump” you feel on longer climbs and building the aerobic pathways essential for recovery between sessions and hard attempts.
How I Use It to Aid Recovery (While Injured)
For rehab, the grip trainer is a safe easy option. After finger or wrist injury, high loads are dangerous — but light, controlled movements stimulate healing.
Rehab example:
- Volume: 2–3 sets of 2–5 minutes daily.
- Repetitions: Gentle squeezes with slow release.
- Rest: 1–2 minutes between sets.
- Key focus: Improve circulation, prevent stiffness, and rebuild tissue tolerance.
Using the grip trainer as part of a climbing specific physiotherapy program ensures a full recovery of common finger injuries.
Summary – 3 Actionable Takeaways
- Use it for endurance, not max strength – the grip trainer is best for blood flow, ARC training, and tendon health.
- Rehab safely – add gentle, daily squeezes to rebuild strength after finger or wrist injuries.
- Make it portable – keep one in your bag, car, or desk to sneak in recovery and endurance training anywhere.
