Get Ready for the Best Years of Your Life

The trainers at Active Age Fitness are experts on aging and functional fitness. They are all certified through an NCCA organization and more importantly – are all certified Functional Aging Specialists through the Functional Aging Institute.

They are always learning. Active Age Fitness continually seeks out scientifically-based, proven methodologies to inform its training methods. Its training programs use methods from the Functional Movement Screen, Smart Group Training, and FallProof systems.

“I am fitter, stronger and healthier. Off my diabetes and blood pressure medicines and no longer have a fatty liver! My doctor asked me how I did it. Dina and her training!”

We're Going to be Living Longer

If you aren’t moving well now, you aren’t going to be moving well later in life as you age. Watch this video to hear about how we can help you get fit and healthy!

Our Training Philosophy

We believe that exercise should support the activities you are passionate about doing every day.

That’s why our mission is to enable you to do the things you need to do, like to do, and want to do with greater ease and enjoyment – for the rest of your life.

We specialize in functional fitness personal training for boomers, seniors and those with medical conditions. Functional bodyweight resistance training is scientifically proven to be the most effective way to build muscle, strengthen the core, and burn fat – no matter the age. Training with one of our Functional Aging Specialists will allow you to pursue life with greater strength, energy, and vitality.

Whether you are training one-on-one or in a small group of up to 5 people just like you, each 30-minute training session is geared to your individual fitness level and abilities – no matter your previous fitness experience.


I am getting stronger, my balance is better, and I am able to use what I learn daily.

Ruth, Sunnyvale

I am probably in the best shape that I have ever been, EVER. I feel so much better physically and mentally.

Lisa, Sunnyvale

I can now touch my toes which I could not do before. This workout gives me more mobility than I have had in years. 

Loretta, Sunnyvale

In three months I am already dropping dress sizes and have so much more energy and stamina.

Helen, Cupertino

We are committed to helping you achieve dramatic results.

Whether it’s to move better, feel better, look better, have less pain, be stronger, feel more confident, improve balance or lose weight, we have the expertise to get you there.

If you want to age your best, you want to be working with Active Age Fitness!
