Therapy patients can use the comfortable weights instead of dumbbells. They were developed by a patient in physical therapy who was having difficulty grasping the 2-lb dumbbell prescribed for her. She wanted something that would conform to her grasp, be comfortable, and be unintimidating. They are also great for light workouts. With the following attributes: easy to grip; comfortable to the touch; soft, but not floppy; unintimidating; color-coded to indicate weight; store on standard cuff weight rack; inexpensive; made in US by makers of the cuff weight; carry a 1-year warranty.
