![]() Isometric exercises are contractions of a particular muscle or group of muscles. For example, as a person performs a squat, there is a moment at the bottom of the squat when movement ceases before returning to a standing position. The isometric portion of any movement occurs when moving around a joint is stopped, which often occurs before the start of the next movement. Examples include the plank and the side bridge, and bar hang. What is the isometric phase exercise?Īn isometric exercise is any strength-training movement where your muscle length and the angle of your joints do NOT change. Isometric actions are ones in which the muscle attachments closest and furthest from the center of the body (proximal and distal) remain at a constant length. In Part 3, we’ll examine the isometric phase-the phase in which absorbed eccentric energy turns into explosive, concentric actions.
