Often measured by a dynamometer, your grip strength is an important measure to consider as it gives you information about your upper body strength; for instance, lower scores tend to mean a weaker upper body. A strong grip is important as it makes aspects of your daily life (opening jars, walking the dog, etc.) easier and is essential for certain sporting activities (i.e. rock climbing, golf, etc.).Typically, grip strength will improve with improvements to upper body strength.
