Hey water fitness fans! These Eanpet aquatic dumbbells are about to make your pool workouts way more effective. Each set comes with 2 lightweight barbells made from durable EVA foam that only weighs 4.5oz each - but don't let the light weight fool you! When you're in the water, these babies create serious resistance that'll give your arms, shoulders, back, and abs an amazing workout. Measuring 10.8 x 6 x 6 inches, they're super easy to handle and store. Just remember to let them drain properly after use - we recommend standing them up in a tray so any water can drip out. The best part? Water workouts burn calories like crazy, and the more resistance you add, the more you'll burn. Perfect for anyone 14 and up looking to tone up without putting stress on their joints. Whether you're doing water aerobics classes or just working out on your own, these dumbbells will take your aquatic fitness to the next level. Just one quick safety note - these aren't flotation devices, so please don't use them to keep yourself afloat. Get ready to make a splash with your fitness routine!
