Note: These wall-mounted sandbags are hollow and require filling by the user. It is recommended to fill them appropriately; if using sand or other heavy materials, do not overfill to avoid affecting performance. Wall targets are easier to carry than traditional hanging sandbags and can be mounted on a wall or placed on a stool. The wall target absorbs impact through the entire wall structure, providing greater stability compared to freestanding sandbags, which can shift upon impact. This allows for more effective training of punch penetration and overall striking power. Wall targets are commonly used in martial arts such as Wing Chun and Jeet Kune Do. Bruce Lee used wall targets extensively as a primary training tool during his lifetime. He often arranged 2-3 sandbags vertically (known as "two-cut" or "three-cut" setups) or hung multiple bags on a wall, filling them with different materials such as sand, gravel, beans, steel shavings, or iron sand to simulate varied resistance and improve sensory feedback during strikes. This punch training sandbag is designed to help develop proper striking technique, fist conditioning, and boxing combinations. When practicing, stand approximately 17 inches (45 cm) from the bag. Use the elbow to generate power while keeping arm muscles relaxed. Do not tense up during punches. Perform strikes in sets of fifty. If pain occurs, stop immediately. Kicking sandbags are used for advanced skill development, particularly footwork training. When kicking, coordinate breath with movement and maintain balance throughout the sequence, avoiding placing the supporting foot down during kicks.
