YY Vertical Mono Grip Trainer - Single-Finger Pocket Training Tool

The YY Vertical Mono Grip Trainer is a 30g wooden block with a single mono pocket for isolating one finger at a time. It's for climbers who want to correct strength imbalances, strengthen weak fingers or rebuild after a pulley injury with real precision.

Suspend it from a bar, rope, strap or tree branch, or use it on the ground with weights or a resistance band for no-hang and assisted work. At 6 × 4.5 × 2.5 cm it genuinely fits in a pocket, so it comes to the gym, the crag, the train and the office. The recycled rubber wood has a soft, rounded shape that hugs the finger and won't irritate skin over several sets.
