And the emphasis is on the concentric portion of the lift. Think of this as the up portion of a bench portion or a squat. This is the part of a contraction when a muscle shortens or contracts. And it’s what most people think of when a muscle works. But there are two other parts of a muscular contraction which are the eccentric and isometric.

The origin and When you think of a muscle contraction, you usually think of a muscle getting shorter, which is called “concentric” contraction — but that’s not always what happens. We can also do “isometric” contractions, in which there’s no change in length, AKA “clenching.” A concentric muscle contraction is a very common kind of muscle contraction. It is part of many basic physical exercises and everyday activities. Some people use free weights to build muscle.Concentric (Positive) Contractions: Put simply, this contraction shortens your muscle as it acts against resistive force (like a weight).
