The Airex Hand Trainer is the latest tool to become part of the Airex family. Its anatomically-friendly shape makes this ideal to strengthen the muscles in the fingers, hand and arm. The trainer can be pressed with individual fingers or the entire hand, allowing for the individual training of the finger muscles or the complete hand musculature. Using the whole hand when you press the trainer sees the forearm and upper arm musculature get activated. Designed for use in occupational therapy and physiotherapy to aid in development of building muscles, hand-eye coordination and to improve movement. These trainers improve grip strength, so important for athletes and non-athletes alike. Made from easy-to-clean, closed-cell foam with an "integrally molded skin" for extra toughness. Rinsing after use with fresh water is all that's needed. Users then just shake off the excess water and allow to air dry. The trainers are Latex-free and are sized at 5" x 2.4" x 1". These hand trainers are blue. The hand trainers are water-safe and suitable for water therapy and other water-based exercises. Use these anytime, anywhere. In front of the TV, reading, outdoors at the beach, indoors on the couch. If you're ready to squeeze, you're ready to go. Ideal for everyone: Beginners, seniors, patients, athletes, children and everyone else! Feeling tense? These trainers double as a great stress reliever. Once cleaned, please note, damp products should never be stored in lockers or stacked in confined spaces.
