That shot was using a 16-35 f2.8l on a 7d. Settings were 1/320, f3.2, iso 2500, focal length 16mm
Our "home" gym's lighting is horrible with all kinds of uneven lighting which makes it tough to find one setting to stick to. I'm constantly adusting depending on where I'm at in the gym. At other schools I'm finding that I can get pretty decent stuff at 1/250 and 1/320 shooting wide open at 2.8 with the iso usually right around the 2000 mark.
