Color Coded Rubber Hex Dumbbells from York Barbell are available in smaller weight increments from 2 to 10 lbs and are brightly color coded by size for easy identification during free weight workouts. These versatile and durable rubber hex color dumbbells can be used in place of vinyl dipped or neoprene dumbbells in areas of extreme use, like commercial environments, and are great for total body toning, strengthening, and muscle building. York Rubber Hex Color Dumbbells offer all the lighter incremental sizing and color coding benefits of smaller aerobic dumbbells combined with the more generous hand grip, structural integrity, and commercial durability of a traditional full-size rubber hex dumbbell. Don't let the attractive colors fool you...York all-purpose color dumbbells are perfect for all weight training exercises and strength training routines. Each York rubber encased dumbbell includes a thick coating of rubber that helps protect dumbbells, gym floors and other gym equipment from impact, scuffs and scratches, and also dampens noise and vibration during use. Each head is hexagonal in shape which keeps your dumbbells from rolling off your dumbbell bench or across the floor, and also provides a stable foundation for ground based exercises such as push-ups. Ergonomically shaped contoured handles are shaped to fit the palm of your hand to better disburse the pressure while completing pushing or pulling exercises. Applications include home gyms, aerobics and cardio strength rooms, hotel workout centers, personal training studios, group exercise classes, women's fitness studios, fitness boot camps, senior care facilities, and rehabilitation centers. Maintenance free with no bolts to come loose or tighten. 1-Year commercial warranty against manufacturer defects. Warranty does not include rubber or chrome.
