YY Duo

The Duo is a featherweight accessory designed specifically for climbing training, isolating the muscle and tendon development for one and two-finger holds.

Featuring a two-finger pocket (25mm deep) and a mono hold with a piece of cord for easy attachment. The Duo can be used pre-climb with a resistance band or light weights to warm up the fingers. Or you can apply them to a more intensive training programme by incorporating them into a fingerboard session or using them to lift heavier weights to build finger strength.

Compact and great quality

I am very pleased with the feel of the YY Duo, it is a nice, solid piece of equipment. The packaging clearly states the weight limit of 45kg, which is very handy to know. I use it once or twice a week to build up my two-finger crimp strength and I have no criticisms. The mono part of it is also very handy.
