Dumbbells are used to exercise all major muscle groups, including arms, chest, back, 
abs, legs and core. The benefits of dumbbell exercises include muscle building, improving 
core strength, boosting balance, providing better bone health, burning calories, increasing 
energy levels, enhancing overall mood and more. Dumbbells are perfect for training 
individual muscle groups or major muscle groups, HIIT workouts and walking. Built for 
durability, safety and comfort, the CAP Neoprene Coated Dumbbell Weights have an iron
