This 45-minute, boot-camp workout for ages 15+ is a full-body strength circuit workout that engages every muscle group for improved all-over strength and calorie burn. Cardio intervals keep you moving – and sweating – throughout the entire workout. Each session includes warm-up, timed stations, and a cool-down. During the good-weather seasons, we hold workouts outdoors to take advantage of the fresh air. Bring plenty of water and a towel.
