Some of the hardest forms of exercise we could do are found in the transition from concentric to eccentric muscle movement. The difficulty lies in that the muscles move in a different way so the exercises feel different but muscle fatigue still piles up. This also means that the adaptive response of the body kicks in. Untamed is a workout designed to make you harder to...well, tame by fatigue. Add EC. Do not be shy.
