Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In addition to the major trial and primary investigation described above, an exploratory Substudy was conducted separately to begin to evaluate the initial "proof of concept" of a food literacy curriculum in 2 separate community centers that were not part of the major trial. This first-generation exploratory Substudy is not part of the major trial and therefore is not included in this protocol and trial description.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Promotora for physical activity
Weekly sessions with a volunteer promotora at a community center. A promotora is a trained, lay health worker. The promotora will provide guidance, advice and support to participants to encourage them to be more physically active.
Promotora for physical activity
A promotora is a trained, lay health worker. Promotoras will be trained and supervised to provide advice, support and guidance to people to encourage them to be more physically active. They work with people face to face and by telephone to offer support and advice.
Carmen system
Weekly sessions with the virtual advisor accessed through a computer located at a community center. Carmen is the virtual advisor and will provide guidance, advice and support to participants to encourage them to be more physically active.
Virtual Advisor
The virtual advisor is named Carmen. She is an animated, computer-generated figure that speaks to participants and gives advice and support for physical activity.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Aged greater than or equal to 50 years
* No plans to move within the next year
* Inactive (have not engaged in moderate-intensity or more vigorous physical activity
* \> 3 days per week for at least 20 min per day) within last 6 months
* Able to participate in study intervention and assessments at their local neighborhood senior center
Exclusion Criteria
2. Not stable on their medications, including hormone replacement therapy, for ≥ 3 months (given that changes in medications can create additional stress and burden over and above attempts to change lifestyle behaviors);
3. Inability to complete a face-to-face training session with a computer-based program
