Enhanced spatial awareness, fitness, smiles – trampolining is the perfect summer sport. It will help you eliminate the backflip to scorpion from your repertoire and make your core muscles glisten like those of a Health and Fitness cover model.
The only real downside with trampolining is that core snowboarders will accuse you of cheating. If you were a proper snowboarder (who are almost as grumpy as proper skateboarders) you would eat shit for months in order to learn your triple corks / frontside fives. Practising on a trampoline makes you a really weird combination of being both a pussy and a jock at the same time. Which pretty much makes you a rollerblader.
Still fun though. Especially if you do it in lycra with fluorescent leg warmers.
