Why does Fastercise focus on building up mitochondria?

Fastercise focuses on building up the size and number of your mitochondria through both Shivercise and Tightercise to help shift your body away from “storage mode” and toward “forage mode,” away from using food to build up your fat stores and toward using up your fat stores to obtain food. This laser-focused approach is designed to not only help you get quick resultts (in 1 or 2 weeks of trying the program) but also to help shift your body’s tendencies so you may experience fitness like you’ve never achieved before that you can easily maintain.
