Staying fit is imperative for good health and well-being. Unfortunately, some people use old age and brittle bones as an excuse to stop keeping in shape. But.

It doesn't really take much effort to remain fit. In fact, you don't even have to get out of your chair! Several San Diego programs help improve the strength, balance and vitality of older people with simple exercises -- many of which can be done while sitting down.

Chair exercises are slow movements, such as rolling your shoulders or stretching your hands above your head. They might sound simple, but don't underestimate their physical and mental benefits.

Zoraida Fink, a nurse who teaches chair-exercise classes at Wesley Palms Retirement Community, emphasizes improved vitality and range of motion, as well as pain relief and mind improvement.

Resident Magda Jokl, a two-year veteran of the class, says she appreciates her improved flexibility and balance. "Many older people don't have the balance to do exercises like this while standing," Jokl says. "The program also decreases isolation."

Or take Emma Kniseley, 86, who says, "the class is so enjoyable, the seniors want to exercise." Kniseley herself recently recovered from a four-way heart bypass.

Meanwhile, over at the College Avenue Senior Center, seniors are reaping the benefits of a similar program called the Feeling Fit Club. The wellness class, created by Aging and Independent Services, is available at 25 senior nutrition sites around the county. Besides balance, the exercises are designed to increase strength. The classes also increase social interaction, while helping participants remain independent longer.

Many exercises are designed specifically to simulate real-life situations -- getting on and off the toilet, reaching for things on high shelves and driving. While nearly all of the exercises can be done sitting down, participants are encouraged to stand if they are able.

Instructor Katie Judd says she is pleased with the improvements she's seen in some of her students. "Some, who used their walkers more as a safety net, have abandoned using them altogether."

Frequent attendees agree. For Lena Kanner, exercise is nothing new -- she's been doing it since she came to San Diego 25 years ago.

But College Avenue student Fay Antecol sums up the program best: "We love it!"
