Free standing punching bags and hanging punch bags are all very well and good for boxers and kickboxers but those disciplines that require a more targeted approach should consider buying the century BOB range of free standing punch bags. Like all century freestanding punching bags the BOB can be filled with either sand or water. The rocking mechanism is also the same as the market leading original century wavemaster punching bag. So what does good old BOB punching bag offer that the other punch bags and even real life opponent do not? Well for a start BOB is anatomically correct and modelled on a real human. One can practice stikes such as spear hands to the eyes, panther punches to the throat, elbows behind the ears and more.... you cant do that with your training partner and get away with it. A regular punch bag wont work either... BOB can help and he has no arms so he wont hit you back! Shop at Pad-up.com and get FREE UK SHIPPING on all century BOB freestanding punching bags purchased.
