Working out smarter can help you burn calories after you have finished your workout. High intensity exercise not only helps you lose weight faster, build muscle quicker, and increase aerobic capacity it also increases the post workout energy burn better than other fitness options out there because your body has to work twice as hard to replenish and recover itself.
When you engage in high intensity workouts your body needs to take in oxygen at a higher rate than it did pre-workout, so that it can repair, cool down and get back to a state of resting. Your body and metabolism are working at a much harder level for this period of time and it is burning up energy in the process. The technical name for this process is EPOC (excess post-exercise oxygen consumption) and it can increase the calories you burn by 6-15% although the exact amount depends on the individual and can last anywhere from 16 to 38 hours.
Whilst your body is recovering from high intensity exercise it is also building muscle mass which is using further energy to break down and rebuild the amino acids. Your body is continuing to work and consume energy well beyond the actual workout, but the key is within the style of exercise. If you’re working out to a low to moderate level you can imagine your body doesn’t have to work as hard to repair itself compared to pushing yourself to a point where your muscles are feeling fatigue, your heart is pounding and your sweating it out. Bursts of intense exercise combined with short rest periods push your body to work and recover faster and this action itself is naturally consuming more energy and burning calories faster.
When it comes to high intensity workouts it is just as important to let your body rest and recover. Your body needs time to replenish and rebuild. If you’re new to high intensity exercise then starting out in a class setting might be best for you, so you can learn how far to push yourself in a controlled environment. Incorporating a little help from technology can also help you to reach new highs with your fitness goals, a device like the MYZONE belt in addition to high intensity classes can help you identify when you get into the “after burn” zone and maximise the effectiveness of your workout.
