Eccentric contractio: Concentric muscle contraction is contracting while you are pulling weight toward you. Eccentric contraction is muscular effort while the muscle is stretching in the opposite direction. Great for building strength, but i high risk for muscle strain, or even tears! must be carefully done and taught! like slowly resisting going down on a chin bar!
