- This is a model, we should clarify, of five pounds of fat.

Rosalie, come on up here and just hold this five pounds of fat.

And just tell me if you think it's heavy or not.

- Oh, Marvin.

- Oh, Marvin.

Oh, Marvin, she said.

- [Narrator] The AFRESH Health and wellness program encourages adults aged 50 and older to form habits they find manageable, because these small incremental changes to diet and exercise can really add up.

- Part of this program is about helping people turn it into daily habits.

That's what we're trying to get to happen in our participants, is something that they can do that's simple and easy, that makes sense, that they can turn into a habit.

- Started out walking one time around the building.

Then I started increasing it.

Until I got up to four miles.

I never pushed too far in the beginning.

- It counts our steps.

And at the end of the day, you write your steps down, that you have done for that one day.

And that keeps me motivated.

- [Narrator] Participants have seen that exercise activities don't have to involve treadmills or stationary bikes.

They've engaged in creative ways to put their bodies and minds to work.

- Even on the weeks that we're not running an actual AFRESH program, we're here and we do some type of class or activity with the residents.

And so one of the things that we did was a scavenger hunt and we gave them a list of just items out in nature.

The idea behind it was it was getting them outdoors.

It was getting them walking and it turned out to be a really fun project.

- The scavenger hunt to us, it was a motivation to get up and do.

We had to find bark, leaves, fluffy stuff, last but not least, just junk grass.

Just like being on a treasure hunt.

- I see this as a public health intervention because it's simple, it's low cost.

And so I'm really interested in testing it further in the future.
