This pilot study evaluates the feasibility, acceptability, and preliminary effectiveness of Lion Hearts, a community-based, family-centered physical activity intervention designed to improve cardiovascular health among mother-child dyads. Developed through community co-design, the 12-week intervention is delivered in local CrossFit affiliates and includes twice-weekly fitness sessions incorporating functional movement, goal setting, teamwork, and health education. The study aims to assess changes in physical activity, fitness, and cardiovascular health markers, as well as family dynamics and motivation for physical activity. Participants complete baseline, mid-, post-, and 3-month follow-up assessments, including surveys, fitness testing, accelerometry, and optional lab work. Findings will inform the refinement of the intervention for future large-scale trials.
