Nobody is born a surfer or an athlete in general. You have to exercise, adopt the right diet, and push your body hard to get good in any sport. This Surfing Experience Core Trainer helps you become fit by giving you the same muscle-toning, full-body workout that you would get with surfing.
Here is how this works: a surfboard is attached to semi-inflated exercise balls that shift as you move. The board tilts and forces muscles in the legs, arms, and abdomen to work. The surfboard three levels of stability, so even beginners can get something out of this. Not cheap but looks fun.
