isometrics

Isometric exercises involve muscle contractions where the muscle length remains unchanged while tension increases, meaning you exert force without moving your joints. For example, holding a plank or pressing your palms together tightly are isometric actions. These exercises help build strength and stability without any movement, making them useful for injury recovery or when joint movement is limited. Since the muscle length doesn't change, they can be performed in confined spaces and are often incorporated into rehabilitation or strength training routines to improve muscle endurance and support joint health.
