Ok, maybe you’ve about HIIT (High Intensity Interval Training) or you’re not quite sure what it is. Basically, it’s doing some type of cardio for a shorter period of time, with shorter rest periods or slower active recovery then bursts of high speed or intensity!
There are many variations of this that can be utilized. For example, if you go to a field and do sprints. Maybe you sprint for 40 yards then job back and do it again for 8 times. Sprint, jog back, repeat.
Another example would be on an elliptical machine. You could go for 1 min on a resistance of 6, then crank up the resistance to 12 for 30 seconds and repeat that for 15 min.
So, you could take just about any cardio, exercise, etc. and use the above formula. As you become more fit, you can increase distance, duration, speed, resistance, etc.
Why do HIIT? HIIT is very effective in many ways. It’s takes less time (my favorite), really challenges you, burns a lot of calories, revs up your metabolism, increase your VO2 Max (oxygen intake/cardiovascular system) and gets you in great shape!
Start off slow and gradually increase your variables while tracking your results. And do different things! Variety is the spice of Fitness!
