If you want to increase your key fitness metrics in an efficient manner, this plan is for you. The 8-Week Fitness Builder is focused on boosting high-end fitness (aerobic capacity, threshold and force) as well as technique (pedal stroke, cadence and efficiency). It commences and ends with a built-in threshold heart rate test (protocol included). The plan is targeted towards individuals looking to maximize gains efficiently and works best when most of the workouts are executed on an indoor trainer. It is a great intermediate build for a Sprint or Olympic triathlon, or serves as a great early season base block for long course racing prior to the specific preparation phase of training.
