A hanging punching bag is a piece of equipment used for boxing, martial arts, or fitness training. It's a heavy bag made of durable materials like leather or synthetic materials, filled with dense foam, fabric, or sand, and suspended from a ceiling or sturdy overhead support using chains, straps, or ropes. Hanging punching bags come in various sizes and weights to accommodate different training needs and skill levels. They're designed to withstand repeated strikes and provide resistance for developing punching power, speed, and accuracy. Hanging punching bags are popular in gyms, martial arts studios, and home workout spaces for solo training and group classes.
