Long before fitness became mainstream and research confirmed its role in longevity, Tanako Hagiwara was already teaching older adults the power of movement. Her Body Dynamics class originally started as a popular senior course at City College of San Francisco (CCSF). When CCSF discontinued its older adult program, On Lok 30th Street Senior Center began to offer Tanako's class as part of its activities, and today it is still a big hit with seniors.

A lifelong advocate for physical activity, Tanako started teaching at CCSF in 1967 and earned her PhD in Exercise Physiology, Kinesiology, Motor Learning and Higher Education from UC Berkeley in 1973. Now at 86, she remains a dedicated instructor, leading seniors in movement and exercise every Tuesday, Thursday, and Saturday from 10 a.m. to 12 p.m., in the senior center's garden.

Many participants joined the class after experiencing health setbacks and while recovering from surgeries, strokes or other conditions affecting their mobility—and they credit it with transforming their lives. "I could see my health improving after I started Tanako's Body Dynamics class," said Arlene Diaz. "She covers everything: stretching, weights, balance, aerobics. Her energy and passion inspire me, and I love being outdoors with others."

Bari Ness said the class is more than just a fitness routine for her: "It's really helped me get in better shape and heal from surgery. The exercise is just the right level for me, and the sense of community is incredible," she said.

Ana Rivera and her husband, Irving, can personally attest to the program's impact. "Tanako is more than a teacher- she's our mentor and our salvation," Ana said. "After a motorcycle accident left me in a wheelchair for a year, doctors said I'd never walk unaided again. Thanks to Tanako's guidance, not only did I regain my mobility, but today my husband and I lead our own Zumba class at the senior center. We've seen so many others recover just like we did. The best gift we can give our bodies is to keep moving and stay healthy."

Beyond physical recovery, the class is an opportunity to connect with others and make new friends. “I’ve watched participants come out of their shells socially, just as I have seen people transition from walkers to canes, and from canes to walking freely. The energy I receive from this group is incredible, and we all feel it," said Tanako. What is the secret of her own vitality? "Exercise, good nutrition, staying engaged, and being together. Most of all, I love what I do, and I guess it shows.”
