Adding Water Wrist Weights by Water Gear is a simple, yet highly effective way to add resistance to your underwater workout. They are made of Lycra and are covered in a neoprene jacket so that they are more comfortable to wear. They can be worn for aqua aerobics, physical therapy, or just regular swimming to help build strength. The weights come in pairs and color coded by weight. The 1 lb weights are purple, the 2 lbs wrist weights are light blue, and the 3 lbs weights come in a darker shade of purple. Feel free to contact the pros at PoguePoolSpa.com for more information.
