Marianne Morrill, a third-degree black belt in Kenpo karate, looks like the quintessential kickboxer: tall, lithe and graceful with short brown hair.
The 50-year-old opened AKKA Karate 3 1/2 years ago.
One recent evening, she and eight students busted out eight jumping jacks, push-ups, squats and crunches while jogging in between.
"I think I push them to try to be better, but I don't make them feel bad for what they can't do," said Morrill, who estimated she works out with her classes and her own Kenpo training six hours a day.

Every Tuesday evening, the facility offers a free workout that features P90X, Insanity and TurboFire workouts.
Suzie Carlson, 34, started kickboxing at Focus Fitness in December.
"I was looking for something to help me lose weight," she said, describing the classes as high-intensity, fun and energetic. "I fell in love with it; I really enjoy the Turbo Kick class. I bought TurboFire, too."
Carlson has lost 34 pounds since December, mainly from kickboxing and watching her diet.
"Before I had been doing other exercise plans, and I hadn't really seen any results," she said. "(Before Turbo Kick) I had really been trying to lose weight for three years."
She likes that the class requires no equipment.
"We just use own bodies," she said. "We're punching air and kicking air and keeping moving every second."
