Now in her early 50s, Paula Maccabee feels she is more physically fit than when she was in her 30s.

"I have more endurance, more core strength and great balance. My cardio capacity is greater and I have retained my flexibility," Maccabee said.

What's her secret?

"I've been training in the Korean martial art of taekwondo three to five times a week for almost nine years. For the past several years, I have also studied the Japanese martial art of aikido about twice a week," Maccabee said.

"I use cardio machines and lift weights at the gym, take long walks, jog and do various yoga-based stretching exercises for more balanced cross-training. I work out every day, but with the inspiration of the martial arts and the variety of different challenges, training never becomes stale."

A third-degree black belt in taekwondo, Maccabee has a dedication to being fit, something more baby boomers are finding beneficial as they age.

According to the International Health, Racquet and Sportsclub Association, regular physical activity helps prevent and reduce the signs and symptoms of arthritis, Alzheimer's disease, diabetes, osteoporosis, heart disease and certain types of cancer.

So how can baby boomers, from martial arts experts to those just trying to get off the couch and into the gym, find a balanced workout to stay healthy?

Staying Fit To Enjoy Everyday Activities

Robert Reames, Gold's Gym Fitness Institute expert, personal trainer and nutritionist, says fitness is about more than exercise.

"You want to be able to live and function and feel good," said Reames, who has appeared on "The Ultimate Weight Loss Challenge" and "Dr. Phil."

He added that as people age, they want to be able to handle everyday tasks such as picking up their grandchildren, lifting items into a closet, walking up the stairs or shoveling a driveway.

The key to achieving a level of fitness to perform these tasks, Reames said, is to have a balanced workout.

"The keys to fitness are strength, flexibility and cardiovascular, and balance is a big part of it as well," Reames said.

Maccabee said she can feel the benefits from her balanced workout in her daily activities.

"I feel energetic, strong and flexible," Maccabee said. "I can keep up with my teenaged son, dance the whole night at my daughter's wedding and hike all day in the mountains with my husband."

Types Of Activities

Reames' main recommendation is simple, yet he said it can also be very beneficial: "Do things that you know you can do and that you're good at."

And also do what you enjoy.

Maccabee said she used to use exercise as primarily a way of maintaining her weight, which she said "became drudgery, and it was hard to stay motivated."
