Tension Climbing adjusted the edge profiles and added new 8mm and 10mm edges to make the Flash Board even more comfortable and versatile as a warm-up and portable training tool.
The Flash Board was born out of necessity. After travel-induced lapses in training and many climbing sessions undermined by a lack of good warm-ups, Tension knew they needed a solution. The compact, cylindrical design makes the Flash Board light, easy to pack, adjustable, and extremely resistant to rotation. Hang it from a pull-up bar, a sturdy tree, a bolt, or pull against the resistance of a solid object or your own foot! This is one tool you don’t want to be without. Just don’t pack it in your carry-on luggage… the TSA doesn’t love that.
