Army Training at High Intensity Study

Constantly varied functional movements performed at a high intensity and incorporating monostructural (aerobic), gymnastics (body weight) and/or weightlifting movements. CrossFit is a good model of HIFT for the military because of its emphasis on general physical preparedness and functional movements and because it is open source and programming is available at no cost (see www.crossfit.com). Sixty-minute HIFT sessions will include a warm-up, workout and cool down. Workouts will average 15 minutes in duration (range = 5-45 minutes) for a total of 50-100 minutes per week.

Usual physical training program for Army personnel from directive FM 7-22, using the Reset phase. Exercises will address strength, endurance, and mobility training. APRT is designed to be completed in 60-90 minute sessions, 5 days/week for a total dose of 300-450 minutes per week.
