Those Dahm triplets are back in the video business, and this time they keep their clothes on.

Erica, Jaclyn and Nicole Dahm, whose cozy December 1998 Playboy centerfold and subsequent soft-core porn video created a tsk-tsk buzz around their hometown of Jordan, Minn., are promoting a newly released video for new mothers trying to regain their slimmer figure.

"In just three quick and easy 10-minute workouts you can tone lean arms, sculpt sexy abs and lift your buns," says promotional material for "3-2-1 Get Your Body Back," which omits the well-chronicled naked truth in their background, which included hitting the clubs with Playboy founder Hugh Hefner.

The 33-year-old sisters all live in the Los Angeles area now and each has a baby girl younger than 18 months. Erica, whose father-in-law is TV's "Dr. Phil" McGraw, is expecting a second child.
