Dana White? I am thinking he could put you through a really awesome boxercise workout....have you do low duck squats to really get them glutes firm.... Hell Yeah.:yep Ok I am going to make this serious. Who would you pay to train under, and how much would you pay....I would pay a good bit to train under Freddie Roach (I am a boxing guy first) but i know i couldnt afford what Roach would charge....in mma...I'd love to do BJJ with any of the gracies...Eddie Bravo would be cool as well.
Actually there are quite a few teachers outside of Gracies that are quite amazing. In fact just because they're Gracie doesn't mean they're a good teacher, not to mention they'll never teach you everything they know.
For me it would clearly be with Greg Jackson's camp. The guy just seems to be a genius, and a master strategist with a great mentality.
