I work in the marketing department for a fitness company in Tampa, FL and every now and then I get to do a photo shoot with the personal trainers. It's always a blast. Here's one of my fitness guru friends striking a post-workout pose.
Image made with a Nikon D300, 18-70mm lens, three flourescent Smith Victor lights and one muscle dude.
Clipped in CS3 and reduced in saturation to meet brand / campaign guidelines.
