Freestanding punching bag combines a 68-in tall target with a stable base so you can practice punches and kicks without wall mounting. The base can be filled with sand or water to add weight, while 12 large suction cups help hold it in place on smooth floors during training. Four strong springs between the bag and base let the bag rebound for continuous combinations and an enlarged silencing layer helps reduce noise. Multi-layer construction provides a wear-resistant, waterproof, easy-to-clean surface.
