What is HIIT Training?


Why HIIT Training is better than hours of cardio


HIIT is a training strategy that gives you short bursts of intense exercise followed by active recovery periods. You can perform 30 minutes of HIIT and achieve the same benefits of one or two hours of cardio. Perhaps the time factor is one of the most important aspects of HIIT because a lot of people don’t get enough time to train for hours.


Here’s why HIIT is a better choice when compared with steady-rate cardio:


It gives you a greater after burn HIIT burns more fat and increases your EPOC (excess post-exercise oxygen consumption), also called an after burn. This means that you expend more calories after your workouts for up to 24 hours and maximize fat loss. This isn’t something you can get from steady-rate cardio exercises.


Your heart rate should go up to 85 percent of your target rate while you perform HIIT. This is followed by an active recovery stage where you perform a less intense exercise.


It’s short! The World Health Organization recommends exercising for 30 to 45 minutes daily (for adults of ages 18 to 64). Furthermore, when you perform lengthy workouts, for example for 2 hours straight, your body begins to release stress hormones such as cortisol even if you work out at moderate intensity. Cortisol inhibits weight loss and stimulates the body to store fat and retain water.


It increases endurance HIIT elevates your VO2 max, which allows you to utilize more fat as fuel. VO2 max is the maximum amount of oxygen your body can transport and use during a workout. The higher your VO2 max, the more fat you use.


You have much more fat stores in your body than glycogen stores therefore, your aim should be to utilize a maximum percentage of fat from fuel while you work out. Super high intensity workouts such as sprinting use high levels of glycogen and the rate at which your body switches from fat burning mode to sugar burning mode is much greater if you have a high VO2 max.
