This can help improve strength and endurance.Īn advantage of isometric exercises is that they are fairly easy to perform, usually do not require any equipment, and are easily incorporable into many weight lifting exercises. Holding the muscle contraction allows the muscle tissue to fill with blood and create metabolic stress on the muscle.

Some isometric exercises develop tension by holding the body in a certain position, while others may involve holding weights. People will typically hold the isometric contraction for several seconds or minutes. During isometric exercises, the joints are still, and the muscles do not change shape or size.

Many strength building exercises involve concentric or eccentric movements, which are both isotonic contractions.
