FATBURN
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.
CARDIO
This program presents a quick progression up to near maximum resistance level (default or user input
level). It has slight fluctuations up and down to allow your heart rate to elevate, and then recover
repeatedly, before beginning a quick cool down. This will build up your heart muscle and increase blood
flow and lung capacity.
STRENGTH
This program has a gradual progression of resistance up to 100% of maximum effort that is sustained for
25% of workout duration. This will help build strength and muscular endurance in the lower body and
glutes. A brief cool down follows.
INTERVAL
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
programmed to use oxygen more efficiently.
