Here's how Ari Meyers combines "Kate & Allie," Yale and 10 hours a week in the gym. You might think someone who exercies 10 hours a week wouldn't mind skipping a couple of days while traveling. Not Ari Meyers. If she can't go to the gym with weight machines, she unpacks a rubber exercise band and goes to work

It's just one of the ways Meyers squeezes a fitness routine into a phenomenally busy schedule. She plays Susan Saint Jame' daughter, Emma, on CBS' Kate & Allie, is a freshman at Yale, attends aerobics class five times a week and works out in the gym another five hours. Even when choosing a college, she scrutinized the fitness facilities as closely as the curriculum.

"Exercise is such a part of my file. It's like getting up in the morning. If I don't do it, I feel terrible," Meyers says. So it's no wonder she works out every day even though she commutes two hours by train from the New Haven Connecticut campus to New York City at least twice a week to tape the show.

When Meyers went to North Carolina recently to shoot Windmills of the Gods with Jaclyn Smith, a miniseries expected to air in early 1988, she took along her minigym - ankle weights and exercise bands, a resistance device she uses to exercise her legs and buttocks. And she discovered the aerobic benefits of a cross-country ski machine. "I had never done it before, and it's wonderful."

She recommentds varying a fitness routine. "It's better for you if you don't do the same thing all the time because your body gets used to it, and it won't respond."   And change fights boredom she says. But Meyers is not suffering any motivational lag yet. Something she's very excited about is the University's indoor exercise facilities. "They have aerobics there. That's the first question I asked" as a prospective student.

The soft spoken 18 year old has dabbed in weight lifting since she was 12 and discovered aerobics at 13. Meyers begins her gym routine by warming up on a computerized stationary bike that monitors speed, pulse rate and distnace. Then she pedals 35 minutes before going to weight machines. "On the machines, I usually concentrate on lower body, legs, buttocks. And my trainer makes me do upper body...he makes me work all over."

"I try to balance her out says trainer Andrew Bostinoo of 21st Century Nauticus in Manhattan, where Meyers works out when she's in town. "She's in almost unbelievable condition. To give you an example, she can do leg presses with 155 pounds at 30, 40, 50 repetitions and just continue on and on. She doesn't fatigue."

And the workout gives her a mental edge as well. "If I can't get there, I just cry all day," she jokes." Exercise is not semething I do to sculpt my body; it's more for the way I feel. It makes you feel so much better about yourself and you can do so much more. When I don't do it, I don't feel as energetic. It relaxes me when I have a lot to do."
