Thanks for the comments, guys.
Ranie: I would be very interested in JG's post-processing techniques, though I was a bit disappointed to learn that in order to get a peek at them, he wants payment for how-to vids and books.
Suppose I should talk a little more about this photo shoot: The shoot took place in an MMA gym. The main purpose was to get photos to use for web graphics and fight posters, so I set up my chromakey green backdrop (so the background could easily be edited out) and did 6 poses of all the fighters. Then we set up another shoot with part of the gym as a background (shown above). There is a partial cage with only 3 sides with a boxing ring behind it. I wish that window hadn't been there, but I digress. The wall with a bunch of fight posters can also be seen behind.
I set up my Alien Bees B800s w/ softboxes a little behind my subjects with both firing directly towards each other. The lights were about 10' apart, with the light on the left at full power and the other at half. One strobe was placed on the floor @ full power, aimed upwards at the ropes on the boxing ring and cage for some highlights, and to cast some interesting shadows on the ceiling. The other strobe was directly behind camera, also at full power, utilizing a 43" shoot-thru umbrella.
Yes, the fighters are shiny. They are lubed up w/ baby oil to add that little extra zip with some highlights that are enhanced in post.
