9Round

Visitors follow a 30-minute workout built around nine three-minute rounds, with 30-second active breaks between rounds. The sessions combine high-intensity interval training with kickboxing movements, functional weight exercises, and heavy-bag resistance work. Workouts are available on a flexible schedule rather than at fixed class times, and 9Round trainers provide guidance during the rounds. PULSE wearable heart-rate technology tracks effort in real time to help members monitor their workout zones. The format focuses on full-body conditioning, strength building, and calorie-burning exercise. Kickboxing fitness is a specialty, with training designed for participants to work with bags rather than sparring against another person. This 9Round fitness studio is in San Antonio, Texas.
