Once you set a foot inside a combat sports gym, especially a boxing gym, a huge plethora of boxing bags can be found - some brand new while some battered and maltreated. The world may stand to cease but the absence of a punching bag in a boxing gym is something I’m willing to bet my money on.
No matter which gym you choose to set a foot inside, you will spot at least one, unless of course you choose to put my words to test on an extremely low budget gym, in that case I might have a run for my money. Having said that, the crux of what I’m trying to say is that a boxing bag is literally the yin to a boxing gyms yang.
