The anatomical term “posterior” refers to the backside of the body. Thus, the phrase, “posterior chain,” refers to the muscles of the backside of the body, specifically the low back, gluteals, hamstrings and calf muscles.
Posterior-chain exercises involve contracting and lengthening the muscles in a chain-like manner. This is important for athletic movements that require strength, flexibility and fluidity to properly jump, rotate, lift or land.
Training the chain can also help to reduce possible injury caused by weak or improperly functioning muscle groups. In addition, a strong posterior chain contributes to a strong core musculature, which reduces backpain and low-back injury, while also facilitating coordination and strength through the limbs.
