Spinerval Suffer O Rama. Toot toot. Here comes the pain train. The Spinerval Suffer O Rama DVD is your ticket to searing leg pain and huge leaps in cycling performance. Clamp your bike into that trainer, put it up on those rollers, or throw a leg over your stationary bike and get ready to be led through a delightful, torturous journey of threshold works outs, power work, explosive sprint, and highly anaerobic sets. It's brutal, but it hurts so good.
