Which one is better, a hanging boxing bag or a punching bag with stand? This is a question that needs to be correctly answered. Well, it all depends on the amount of space you have. Both these bags are equally good and beneficial. Red free standing punching bag is solidly built and stands tall at 6 feet. The free standing punching bag takes less space and is very convenient to assemble as compared to a hanging heavy bag. The base should be filled with water or sand.
