Once available only to elite athletes, power meter technology on a bicycle is now being used by a wide variety of people, with diverse objectives. Regardless of your age, gender, fitness level or athletic status, measuring work effort is key to reaching fitness and performance goals. However, simply having or using a power meter won't make you stronger. Without the element of knowledge, the computer is just a gadget and one is merely working out on a bike with a power meter. Mad Dogg Athletics unleashes the power of innovation and knowledge with the Spinner® Blade ION and the power-based Spinning® training course for certified Spinning instructors and other fitness professionals. Training should be based on principles of science. Wellness, fitness and performance progress are a direct result of the proper relationship between work and rest. Training with power is not about seeing how much wattage individuals can produce, it is about using a quantified measurement of work to respect the principles of training in order to efficiently and effectively improve. Understanding what power is and how it is measured will help you to understand the overall principles of power and science-based training. Knowledge is power and power is the science of performance.
