No I understand what you are talking about. MMA is multiple martial arts, we are focusing on striking. You can become world champion in mma even if you don't have high level striking because your other skills are high level. That's why I'm using high level boxers as examples. We are talking about striking, not overall mma skill. Yes all gyms do it, but not all gyms do it right. If the pad work they are doing don't transfer over to the actual fights, then it's not being done right. The goal isn't to do it well just on the pads, or to just do those combinations on the pads, it's to also do it live. A lot of trainers/coaches do it right, and their fighters are doing the exact same things they drill and practice in fights. Others have pad work that you never see their fighters ever do in a real fight. That is the difference I am talking about. I'm not saying just do pad work/shadow box/bag work and no sparring. I'm saying all of it is important, and it seems like a lot of people don't understand how important it is. Bag work is important because you can hit the bag as hard as you can over and over again and develop your power punches and punching cardio. You can't hit someone as hard as you can over and over again. If you can't hit pads and heavy bags hard, you aren't going to hit someone hard. You don't automatically gain punching power just because you are punching a person and not a bag/pad.
No the training that Canelo, Lomachenko, and Floyd do is the reason they can do what they do. It's very simple, other fighters don't train the same, they don't do the same training they do at all. If they did, they would be able to do it too.
The focus is never about open workouts, people don't do much in those to not give out info about what they are training on before a fight and it's usually done during fight week so they are also cutting weight and not really doing heavy training. The training I'm talking about is their real training that they do. Boxers all spend a lot of time with shadow boxing/pad work/bag work. More so than mma fighters. I've spent time in both boxing and mma gyms. So I know the difference in how each of the combat sport communities trains. They train vastly differently.
