I moved recently, and I lost convenient access to a boxing gym (and regular gym for that matter) so I bought this wrecking ball style heavy bag along with some adjustable dumbbells to help me stay in shape.
I'm also partial to the wrecking ball bag. I've heard someone saying that it's a damn shame Sly Stalone failed to put one in one of the "Rocky" movies because it would've been a lot more popular. If you're not kicking low this is basically an optimal type of bag to work on. People think of it as a specialist bag because you can train your mobility/head movement better but I immediately fell in love with it for general purpose work. And yeah I've got plenty of space, I love it for training inside fighting, I feel like Lomachenko sometimes only around 50kg heavier and 3-times slower:P
