STRENGTH

Resistance: 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 gluts. A brief cool down follows.

INTERVAL

Resistance: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.
