This is the RipSurfer X, an exercise machine made by SurfSET Fitness. It's a strength training machine that simulates the movements of a surfer out on the waves.
Nick Hartwick, a professional hockey player, invented it after he retired from the NHL. He enjoyed surfing while off-season, but found that he lost his surfing physique while he was occupied with hockey for several months. Men's Fitness quotes him:
“I would quickly bulk up and lose the lean and toned physique that surfing gave me—no other workout could compare. Then it hit me,” says Hartwick. “I’ll design a machine to mimic the workout that I got while surfing. It might not be as awesome as hitting waves but it will keep me in peak physical condition and I will still see all of the benefits to my body.”
The result of his efforts was this unique piece of exercise equipment.
