Well i figured i'd share this because i really did have some fun doing this. I came across a common house fly buzzing around my house today so I got up and started to box with it as it flew around. I find it's great for accuracy and it forces you to move and use your feet as the bug moves and they do move pretty fast. I did have some fun with this so I thought i'd share it with ya, try it sometime lol and if your wondering how the bug made out, it's dead
I would imagine though that this COULD be an alternative to a speedbag or even a step up from shadowboxing as rediculous as it seems.
