You might not realize it, but surfing is an extremely physically demanding sport. Or at least it used to be before the Wavejet came along. Thanks to this motorized surfboard, instead of building up your leg muscles, you can just let the board catch up to those fast moving waves for you. This is great news – as surfers become weak and doughy, it’ll be much easier for the rest of us to meet women at the beach.It’s also good news if you’ve ever wanted to learn to surf – a motorized surfboard is sure to make the experience much easier.

You dont use your legs for surfing (or at least you aren’t supposed to). They cause hydrodynamic drag and you keep your feet out of the water because of this. In other words, its all arms, bro.
