I think it's fairly obvious that BJ Penn is a totally different fighter now than he even two years ago. Of course some of it has to be attributed to BJ Penn's natural ability and evolution as a fighter. However, he was always lacking in the strength and conditioning department. That's not the case anymore as he's gone into the fourth and fifth rounds of his last two fights and looked as fresh as ever. I think a lot of that can be attributed to imploring the Marinovich brothers as a part of his training regimen. I wonder how long it'll be before other fighters begin to implement their methods of training?
