Trainer workouts are to fun as:
a. Cavendish is to climbing
b. Cipollini is to restrained
c. Sagan is to slow
In the past we would of accepted any of these answers as correct. It was a general consensus that the trainer would make you strong, but you would sacrifice a bit of your cycling soul with each hour spent on one. That's what so appealing about the Wahoo Fitness KICKR, the thought that you can gain strength over the winter months and actually have fun doing it.
There are several key factors that separate the KICKR from other trainers on the market, and I believe that these fall into two major groups. The first is the hardware and physical design of the trainer. The second is the software the trainer supports.
