INTERVAL
This program takes you through high levels of intensity followed by recover y 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 hear t rate, followed by periods of recover y and hear t rate drop to replenish
oxygen. Your cardiovascular system gets programmed to use oxygen more efficiently.
CALORIES

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.
FUSION

replenish oxygen. Your cardiovascular system gets programmed to use oxygen more efficiently.
