Heavy bags are large, durable bags designed to hold a significant amount of weight. They are commonly used in various settings, such as gyms, for transporting equipment, or by travelers for carrying clothes and personal items. These bags often feature reinforced handles and sturdy materials to withstand the strain of heavy loads. In the context of fitness, heavy bags, also known as heavy punching bags, are used for training in martial arts and boxing. They help improve strength, technique, and endurance by allowing practitioners to practice strikes and kicks against a solid target.
