  "overview": "CrossFit is a branded training method that combines lifting, body-weight skills and conditioning, usually in coached group classes. Workouts vary, and the coach adjusts the challenge to each participant. Its appeal is broad fitness and a shared session; the experience depends heavily on the local gym.",
