^^Exactly my point. MMA and boxing are two different sports. Cant compare the two. True, no one is close to Mayweather in the boxing department, because there is no need to in MMA. Therefore, you will probably never watch "more" of UFC then. Youll have to develope a whole new love for appreciating the art of MMA all together.
Once again, the video that you posted is boxing training oriented. No doubt it is difficult and keeps mayweather in top notch condition. "Superior" one dimension conditioning...
It is hard to judge conditioning when you are only in the ring for 12 2 min
rounds and only have to worry about your head and body getting hit; as suppose to 5, 5 minute rounds, while distributing your weight equally, having to worry about wrestling, takedowns, clinches, knees, kicks, submissions etc...and all using 4oz gloves.
IMO, i dont think mayweather will be able to keep up with this kind of traning:
