The Wide Boyz Crack Trainer with Soft Grip is a simple, lightweight, two piece adjustable crack system, for home use or training areas within climbing gyms. It can be used as a single unit for crack specific exercises and dialling in your technique or multiple units can be added together to do full boulder problems and circuits. The product comes in a flat packed style which is easily assembled and installed by the user. Soft Grip is provided with this product and can be installed within the assembly process, plus easily replaced at a later date if worn.
Using Soft Grip will provide a grippy and comfortable crack feel. This option is good for Endurance and Power Endurance work outs, as well as working on technique. For a more difficult jamming surface purchase without Soft Grip.
The Crack trainer has two halves which you’re able to set at your desired width. Below are recommended Wide Boyz widths. (The dimensions below are just for guidance and you should set the Crack Trainer to coincide with the dimensions of your own hand/arm/leg/…head?)
