Is This Attainable?

Kensey and I have recently ordered some dussack trainers, so a few nights ago we took to YouTube to watch people using them. In one video, we saw a guy who moved really, really well-- in total control at all times, able to pivot and flow and change directions and stop on a dime, all the stuff you'd want to see out of a higher end fighter. The contrast with the opponent was stark, though the opponent wasn't moving poorly. The difference in juxtaposition was just very obvious. 

As we talked about what we were watching, she asked me: "Is that even possible for me?"
