The terrific tushy of Teresa Truesdale appeared on screen only once, in the 1986 aerobics-themed slasher flick Killer Workout. But her film career didn’t start (or end) there. Teresa’s first role was in the action flick The Danger Zone (1986), and she went on to appear in made-for-TV movies like Bitter Vengeance (1994) and As Good as Dead (1995) and in shows like Hunter and Silk Stalkings. But Mr. Skin will always remember Ms. Truesdale’s smooth tail from her salad days as slasher-bait in Killer Workout.
