Weights are exercise equipment used to add resistance and intensity to workouts, helping to build muscle strength and endurance. They come in various forms such as barbells, kettlebells, and weight plates. Dumbbells, in particular, are versatile handheld weights commonly used for strength training, toning muscles, and improving overall fitness. They allow for a wide range of exercises targeting different muscle groups, making them a popular choice for home and gym workouts. Incorporating weights, including dumbbells, into a fitness routine can help increase muscle mass, improve bone density, and boost metabolism for effective weight management and overall health.
