The only real way to train to launch yourself up a giant climbing wall at top speed is, well, to launch yourself up a giant climbing wall at top speed. However, if you don’t have a giant climbing wall to hand, Lee has some alternative ideas. “The Wall is all about pulling strength, so again I’d recommend pull-ups on an overhead bar,” he says. “Don’t worry if you can’t do a full bodyweight pull- up yet, because you can buy resistance bands that will help take some of the weight off at first until you build up your strength. You also need good mobility, so something like yoga will help a lot with that. And don’t forget, The Wall is tall. If you’re not good with heights now, get used to them.”
