High Intensity Interval Training has been found to be the most effective way to burn fat. Interval training workouts involve doing drills for about 2-3 minutes. During this period you need to work and go as hard as you can until you reach muscle failure. If you do this, you will be working out anaerobically, not allowing oxygen to reach your muscles. When you do this, you build up lactic acid in your muscles. When you accumulate so much lactic acid that your body cannot clear it, you reach muscle failure which, if timed correctly, would be when the drill was over and you took a 30-60 second rest and recovery.
So why do you want to deplete your muscles of oxygen? This does not sound very helpful or like it would work. The facts are that interval training has been proven to raise your heart rate much higher than normal cardio does, burn more calories and for a longer amount of time than regular workouts, increase your resting metabolic rate (RMR), burn calories and increase your metabolism for up to 48 hours after the end of your workouts, and the best for last, do all this in a shorter amount of time than a regular cardio workout.
Sounds great, doesn’t it? Well, the fact is that HIIT is rather intense as the name states. It is designed for those who are already in decent shape. If you are not physically active, and I would say a good rule of thumb is that you can perform 30 minutes of solid cardio, then interval training is not for you, yet. You should start out doing regular cardio and work your way up. Once you can go for at least 30 minutes, you can start to incorporate HIIT workouts into your exercise routines. Back let’s get back to the intensity. Because HIIT is so intense, you should not do HIIT workouts on back to back days. You should at least skip a day in between and not do more than 3 interval training workouts per week.
HIIT is physically exhausting to the muscles so they really do need the rest between days to recover so that you can go your absolute hardest the following day. Another solid point is that if you do not go your hardest doing the drills, you will not be working out anaerobically but rather aerobically, with oxygen. This be it the case, it will be like doing regular cardio and therefore you will not see the results that you want. The results from HIIT workouts are incredible as you shed away the pounds of fat! That’s not the only benefit though. HIIT has been scientifically proven to increase cardiovascular fitness. As you continue to work out anaerobically, aerobic activities will be easier. This is why the professional athletes train using HIIT. So if you are ready to take your fitness to the next level all along the while burning a ton of fat, why not try a HIIT workout?
