Dumbbells offer some advantages over other resistance training derives as they can be firmly held in one of both hands in performing various upper body exercises that challenge not only the target muscles but create the challenge for scapular stabilizing muscles and support muscles for spinal stabilization through core musculature activation. They are used to overcome strength imbalances, are safe for users, and allow for a significant range of movement.
Dumbbells allow the user to take the arm or upper extremity joints through a greater range of motion increasing flexibility as well as strength. Also, many individuals hold dumbbells while performing squats for a solid lower extremity workout.
ProHealthcareProducts.com has multiple dumbbell weights and various weight systems for use at home, in the clinic, and even when on the road.
