At standard boot camp, Cindy motivates students as they perform cardio, muscular-endurance, and plyometrics moves, blended with spurts of calisthenics and core work. She keeps groups small to maximize individual attention throughout this 60-minute workout. At kettlebell boot camp, which is appropriate for moderately active exercisers, iron weights strengthen and sculpt muscles as attendees execute swings with perfect form.

Standard boot camps meet Tuesday and Thursday evenings in Central Park—weather permitting—at 6:30 p.m. and 7:30 p.m. or in a Manhattan studio on rainy days. One-hour kettlebell boot camp meets at John A. Seravalli Park on Monday nights and Saturday mornings. See the full class schedule.
