Bas Rutten with O2 Trainer

Bas Rutten on the O2 Trainer

Any professional athlete knows, that having stamina is THE most important thing there is in competition. Throughout my entire Mixed Martial Arts career, I have never ran out of gas. Like they say, you can have a Ferrari, but when you don’t fill it with gas, it won’t drive. The O2 Trainer will give you stamina like you have NEVER had before.
