Tension Flashboard - Portable Warm-Up & Training Board (8-20mm Edges)

The Tension Flashboard is a compact, portable training board so you never skip a warm-up again. It is for climbers who want a proper finger warm-up and consistent training at the gym, the crag or on the road.

Tension built the Flashboard to fix inconsistent training and poor warm-ups while travelling. It is small and light enough to live in your bag, and the cylindrical shape resists rotation so it feels stable and lets you adjust the angle. Edges run from small crimps through 8mm, 10mm and 15mm to 20mm, with comfortable profiles designed for repeated use. Hang it from a pull-up bar or beam, attach it to a tree, bolt or anchor, use it with resistance bands, or pull against your foot for controlled loading. Choose it if you climb in different places and want one simple tool for everything from light activation to harder finger training.
