isometric exercise,
static pull up hold. Static holds are a great way to build muscle strength and definition. While the repetitions and sets are important, you should also focus on maintaining proper muscle tension during these holds. These types of workouts also help you develop a better mind-muscle connection. They also help your body adapt to the weight you are using, which can reduce the risk of injury during heavier lifts.
A static pull up hold also strengthens the muscles in the back, including the latissimus dorsi (the large back muscle behind your arms). It strengthens your chest, upper back, and shoulder muscles. The muscles in these areas contribute to good posture, which is important for a healthy life.
Static holds are difficult, but they are important for achieving high strength and endurance. You can perform many exercises that are isometric, including the fold-over and the plank. This way, you can build a foundation for explosive movements.
