Chris Sharma, Adam Ondra, Sasha Diguilian, the world's elite climbers all manage to claw thier way up the hardest rock climbs in the world. They spend thousands of hours training, skipping out on dessert, and living just to climb. While it'd be amazing to be a world class climber, having the dedication and the work drive is much harder. Thankfully, a group of level 10 engineers discovered a way that you too can climb 5.15d. Imagine being in the upper echelon of climbing and being able to spend half your training time drinking beer from the couch.
