Comparing group classes, a mobile app, and home videos for inactive young adults
Effects of Different Exercise Approaches on Physical Activity Level and Health Outcomes in Inactive Adults
This study will test whether supervised group classes, a mobile app, or home video workouts better increase activity and improve health in inactive adults aged 18–35 who live in Istanbul.

What this trial studies
This randomized, controlled, single-blind trial will enroll 30 inactive adults aged 18–35 and randomly assign them to supervised face-to-face group exercise, a mobile app–based program, or video-based home exercise. Each program includes aerobic, strengthening, and flexibility workouts performed three times per week for eight weeks. The main outcome is change in physical activity level, with additional health-related measures such as fitness, strength, and flexibility tracked as secondary outcomes. Participants must take fewer than 5,000 steps per day, report under 600 MET‑min/week, live in Istanbul, and meet the study's medical eligibility criteria.
Who should consider this trial
Good fit: Ideal candidates are inactive adults aged 18–35 living in Istanbul who take fewer than 5,000 steps per day, report under 600 MET‑min/week, and can commit to three exercise sessions per week for eight weeks.
Not a fit: People with end-stage congestive heart failure, malignant or unstable arrhythmia, acute musculoskeletal injury, pregnancy, mental dysfunction, a positive PAR-Q response, or those lacking adequate technology/infrastructure are unlikely to benefit or be eligible.
Why it matters
Potential benefit: If successful, the most effective format could give inactive young adults a practical way to increase daily activity and improve fitness and health markers.
How similar studies have performed: Similar comparisons have shown mixed results: supervised programs often produce higher adherence and larger fitness gains, while mobile and video interventions can increase activity modestly but usually less than supervised formats.
