When I think of real boxing, and by real, I mean an actual boxing gym getting in your usual bag, double end, speed, etc and most importantly sparring, not nowadays doing boxing cardio classes hitting the bag and classifying yourself as "doing boxing". I think of boxing as a way of life not a hobby. If you want to get good, you need to factor not just all the hours put into the gym but also outside between the roadwork to improve your cardio. When you look at other arts like BJJ, many just do it as a hobby. People with careers, familys, heading over to the gym after work, if they can't make it, no biggie. Don't get me wrong, there's plenty of BJJers who do it for a living. Boxing though, it seems you really need to put it at the top of your list if you want to get good. See that 12 year old in the ring looking sharp at a tournament? He's probably gotten 50 fights already. Now onto sort of main point, is boxing as a hobby and taking hits if you compete worth it if you have no aspirations for turning Pro?
