The free weights on the Gym Visa Gift Card are a familiar sight to gym rats, as well as anyone who has experienced physical therapy. The beauty of free weights is their flexibility. Start small and add weights as your strength increases. Trainers and therapists like them because they don’t limit users to fixed, specific movements. That enables them to help strengthen stabilizer muscles. Athletes of all types use free weights to help strengthen any muscle or group. Give a Gym Visa Gift Card to a friend who works out (or one who needs to).
