STIMULATES THE METABOLSIM
We’ve already mentioned that HIIT relies, among other thing, on starting up the EPOC, which boost up the metabolism for 48 hours after the session. The metabolic boosting properties of HIIT do not stop at this.
Namely, by building your muscle mass it further contributes to calorie expenditure because muscle cells burn more energy than fat cells. Further on, scientific studies reveal that the resting energy expenditure can be boosted by performing anaerobic exercises.
By performing this type of training you rev up the basal metabolic rate (BMR), which is the minimal rate of energy spent by our body at rest during a certain period of time. Increasing your metabolism rate is not only important for losing fat. It will also improve the overall health of your body.
One of the most interesting aspects of HIIT is that it adds versatility to your workout routine, and it can be performed with minimal equipment. Sure, you can include exercises like biking or rowing into your HIIT routine, but many other plyometric exercises can provide you with the same benefits.
As a matter of fact, you can even argue that using equipment can reduce the efficiency of this type of workout, because the main focus of HIIT should be boosting your heart rate and increasing the blood flow to each and every muscle in your body, and not on making one muscle group work harder.
BETTER STAMINA AND MENTAL STRENGTH
Performing demanding physical activities (biking, jogging or lifting weight) for a prolonged period of time requires you to have your body prepared to go beyond its comfort zone, where your hear races and you find it hard to breathe. HIIT can prepare you for this challenge. Namely, according to the scientific research just eight weeks of HIIT can double your performances in endurance sports. By challenging your aerobic and anaerobic abilities, it provides your cardiovascular system with the optimal benefits.
By the same token, HIIT can also be considered as brain workout. Most of us are not used to pushing our bodies to the outer limits of endurance, and as a reason many decide that it’s better to quit. This type of training taxes your body frequently pushing it out of its comfort zone. But once you learn that you can tackle these challenges, you’ll also build up your self-confidence. This will come in handy not only for your future athletic performances, but also in other aspects of life.
