static holds barbell
The static dumbbell hold works almost all arm muscles. They are a great way to strengthen your grip strength. This is important in many sports such as deadlifting and pulling down rebound. This can be useful when fighting for pucks in corners. You can increase your grip strength, and the number of reps that you do without having to drop the weights by using the right technique.
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.
The plank is another common exercise. The plank works many core muscles, including the abdominals. You can also do it on your back with the heels pressed against the toes.
