DENVER—The circuit-training workout offered at Denver-based fitness franchise 1-2-3 Fit burns more than 450 calories in 30 minutes, according to a study released by The American Council on Exercise (ACE). The study found that the 1-2-3 Fit circuit training workout was just as effective – if not more – than other methods of exercise such as playing sports, jogging or lifting weights for 30 minutes.

The study, which was conducted at Swedish Medical Center and in conjunction with the University of Seattle Human Performance Lab, was created to help educate the public about the benefits of efficient and effective workouts, which can help to lower body weight, decrease risk of diseases, and increase energy. The 1-2-3 Fit workout combines cardio, strength and resistance training in just 30 minutes.

“The 1-2-3 Fit circuit training program addresses the top reason that individuals do not maintain active lifestyles—a perceived lack of time,” says Dr. Cedric X. Bryant, chief science officer for the American Council on Exercise. “By blending aerobic and strength training, the program meets the recommended minimum threshold for physical activity to enhance the overall health and wellness of individuals. In addition, the workout offers a wide workout intensity range, which appeals to both men and women, and the group environment provides motivation for individuals and enhances program adherence.”

During the study, data was collected from a highly diverse population over sixmonths. Test subjects ranged from 18 to 62 years old and physical activity levels varied from completely inactive to highly active.
