Loom v3 Expander

The Loom is a compact grip strengthener designed specifically for climbers. It focuses on developing pinch strength, particularly in the thumb, and can also benefit athletes involved in strength training. Instead of traditional springs, the device uses elastic rubber bands to provide progressive resistance starting from 1 kg, making it suitable for both adults and children.

The Loom is especially useful during rehabilitation or load progression after injuries such as flexor tenosynovitis or finger tendon strain. It allows for controlled concentric and eccentric loading of the deep finger flexors in the forearm — key muscles for climbing. The tool supports multiple training protocols, including single-rep maximum efforts, classical strength sets (8–12 reps × 4 sets), and static-dynamic (isotonic) exercises.
