The use of computrainer training allows an athlete or coach to take the guess work out of bike training and racing. When paired up with the athlete’s own bike and our computer, the computrainer can both measure and control the power that the athlete is using to to turn the wheel. In order for a triathlete or cyclist to become faster on the bike, they must train to increase the power that they are able to sustain over a period of time. Using the computrainers at IMF, we can measure the athlete’s current ability to produce power, create a document containing training zones for each athelete, and set up interval based workouts to increase power.
