Building up the corporate body: personal trainer Mike Sapp is pumping up Honolulu's movers and shakers.

Several years ago, Louise Ing wanted to get in shape. But the flashy athletic club scene made her uncomfortable, and she was a little intimidated by guys with big muscles. So what did the prominent, petite attorney do? She joined Gold's Gym, a Spartan haven for Honolulu's muscle-bound, and started

Talk about grabbing the hull by the horns.

Sapp is actually Ing's personal trainer. He meets with her at the crack of dawn three times a week for an hour of stretching, cardio training and stone good, old-fashioned weight training. Under Sapp's guidance, Ing has dropped about eight pounds, and, more importantly, is more toned, fit and energetic. The fifty-something attorney has literally turned hack her Body clock, testing out at a "fitness age" (a measure of strength, flexibility and endurance) of 33.

"Mike's got real-world advice about fitness and nutrition, and he's got a great sense of humor," says Ing, vice president and director at the law firm Alston Hunt Floyd & Ing. "But he's also about the same age, so it's not like a 20-year-old beating up on you, making you do things that only a 20-year-old could do."

Word of Sapp and his successful methods has quickly spread throughout Honolulu's not-so-old boy and girl network. In less than four years, he has built an impressive client list, which reads like a veritable who's who of Honolulu movers and shakers, dozens of high-level executives, lawyers, entertainers and politicians--developer Jeff Stone, Cheap Tickets founder Michael Hartley and Damon Estate chief operating officer Tim Johns, to name just a few. But at $85 an hour, Sapp's expertise doesn't come cheap. This is in addition to the Gold's Gym membership, which ranges from $28 to $48 a month.

"I used to own my own business, so I know what kind of toll working long hours takes on someone," says Sapp, 48. "I know what kinds of demands are on these people. But I tell my clients that being fit is part of their corporate responsibility. If you fail to take care of yourself, you're letting your company down."

Sapp is a member of workout royalty, active in the golden age of bodybuilding in the late '70s and early '80s. He started working as a trainer at the legendary Jack LaLanne Gym in Los Angeles, then was gym supervisor at Santa Monica's Sports Connection, the nation's first superfitness club and the epicenter of the '80s workout craze. In 1980, Arnold Schwarzenegger asked Sapp to be his workout partner in preparation for the role of Conan the Barbarian in the movie of the same name.
