Dumbbells are inexpensive, versatile and easy-to-use weights that let you create a variety of workouts to improve your health. Depending on how much weight you use, the several repetitions you do and the pace at which you use them, dumbbells can help you improve cardiovascular fitness, burn calories, build muscle or increase muscular endurance for sports.
Dumbbells are also prevalently used in injury rehabilitation. They can target specific muscle ligaments in the arms, chest, shoulder, back, abdomen, and legs. Physical therapists have used the dumbbell in rehabilitation for many years to help strengthen muscles like the deltoid and various other powers. The rationale is that strengthening the muscles and ligaments around high-risk body parts like arms and shoulders will help prevent future injuries.
