Brief summary: This feasibility study specifically addresses the issue of adapting US dietary guidelines physical activity recommendations to the population of the Lower Mississippi Delta. The hypothesis is that including a pedometer as a self-monitoring tool as part of adapted physical activity guidelines will result in greater immediate increases in physical activity (as monitored by an accelerometer) than an education program alone.

Detailed description: The purpose of this study was to determine if a short-term pedometer-based intervention results in immediate increases in time spent in moderate-to-vigorous physical activity (MVPA) compared to a minimal educational intervention.A sample of 43 overweight adults 35 to 64 years of age participated in a one week pedometer-based feasibility trial monitored by accelerometry. Participants were randomized into a one-week education-only group or a group that also wore a pedometer. Accelerometer-measured MVPA was measured over 7 days at baseline and post-intervention.

Eligibility criteria: Inclusion Criteria:

* 35 to 64 years of age
* body mass index (BMI) between 25 and 34.9 kg/m2
* being able to walk without limitation

Exclusion Criteria:

* cardiovascular, respiratory, gastrointestinal, neuromuscular, neurological, or psychiatric problems; musculoskeletal problems interfering with exercise
* immunodeficiency problems
* malignancies in the last 5 years
* any other medical condition or life threatening disease that could be aggravated by exercise

Primary outcomes:
measure: Minutes spent in moderate-to-vigorous physical activity (MVPA)
timeFrame: The primary outcome is measured at baseline and after a 7-day intervention period (1 week)
