What do you call that exercise?

Want some more gym terms? I know a guy who pulled a hammie doing hack squats. I also know someone who blew out his ACL while doing deadlifts. (An aptly named exercise in that case.) Rotator cuffs, (no starch needed on these, thank you), are a big problem for many athletes.

Fortunately, as a cartoonist, the worst injury I can claim is repetive stress syndrome with my drawing wrist...And even that hasn't occurred since I switched from brushes and india ink to a Wacom digital drawing tablet a few years ago.
