A U.S. Army coordinator shared a HIIT workout that can boost VO2 max in weeks, improving endurance and heart health [https://www.mensjournal.com/health-fitness/us-army-high-performance-coordinator-shares-a-simple-hiit-workout-proven-to-boost-vo2-max-in-just-weeks]. What's the specific HIIT protocol?
The U.S. Army's High-Performance Coordinator recommends a HIIT protocol of 30 seconds of maximal effort followed by 90 seconds of active recovery. This should be repeated for 6 to 8 rounds, depending on your fitness level. The workout can be done with running, on a treadmill, bike, rowing machine, or ski erg. A light jog or dynamic stretching can serve as a warm-up, and a few minutes of walking and static stretching will cool you down. HIIT workouts, in general, have been shown to improve VO2 max, boosting endurance and heart health. Studies show that HIIT can improve VO2 max and skeletal muscle mitochondrial enzyme production in as little as six weeks.
