During high-intensity interval training workouts, you will fatigue your anaerobic as well as aerobic pathways more than steady-state workouts. By incorporating more H.I.I.T. workouts you will preserve muscle mass when undergoing periods of weight loss. It will also increase your caloric expenditure post-workout, typically between 24 to 48 hours. In short, this workout on the TRUE Alpine Runner Incline Trainer™ will help you burn more calories while still maintaining muscle mass.
With any cardio or running-centric workout, a good warm-up is always necessary to prevent any injury while exercising. Be sure to do some foam rolling or stretching before you hop on the treadmill for this workout, especially if you will be sprinting during the high-intensity portions.
Although this workout only uses the TRUE Alpine Runner Incline Trainer™, proper form is important while you are on any commercial treadmill. When you are jogging or sprinting, be sure to try to land mid-foot to forefoot, avoiding a heavy heel strike during each stride. Hitting with a heel strike can lead to long-term injuries.
Focus on your running form and put forth max effort on the high-intensity portions to reap the greatest rewards. Stay in control at all times when you are on the treadmill to limit your risk of injury. It is okay if you need to use the handgrips while you are working out, especially at higher inclines. Log your speeds used on the runs and sprints and simply repeat this workout in a week or so to see how much better you have gotten.
