This program follows a triangle or pyramid type of gradual progression from approximately 10% of maximum effort (the level that you chose before starting this program) up to a maximum effort which lasts for 10% of the total workout time, then a gradual regression of resistance back to approximately 10% of maximum effort.
Fat Burn Program
This program follows a quick progression up to the maximum resistance level (default or user input level) that is sustained for 2/3 of the workout. This program will challenge your ability to sustain your energy output for an extended period of time.
Heart Rate Control Programs 1 and 2
This program takes you through high levels of intensity followed by recovery periods of low intensity. This program utilizes and develops your “fast twitch” muscle fibers which are used when performing tasks that are intense and short in duration. These deplete your oxygen level and spike your heart rate, followed by periods of recovery and heart rate drop to replenish oxygen. Your cardiovascular system gets trained to use oxygen more efficiently.
The HIIT ("High Intensity Interval Training") program takes advantage of the latest trend in fitness. During this program, you will perform short bursts of high intensity sprinting followed by short rest periods. HIIT is a fully customizable interval training program.
