Cardio is a training that primarily focused on weight loss. It is an aerobic technique that involves different types of exercises such as running, jogging, swimming, treadmill, etc at a steady pace. Your speed and intensity should be consistent throughout the exercise. It has numerous benefits such as:

- Weight loss
- Improves cardiovascular health
- Increase metabolism
- Overall health benefits
Although cardio training has many benefits, it does not come closer to High-Intensity Interval Training or HIIT. It does not mean that doing cardio is not good or has no benefits but if compare with HIIT its benefits diminish. HIIT is far superior and harder than traditional cardio.
HIIT involves explosive movements with short intervals of a fixed time for rest. Exercises of HIIT are built in a way that you will not be able to take a breath while performing them. Take the example of a sprint, In a sprint, you run as fast as you can with full power and if you notice, you will not be breathing at that time.

Due to this anaerobic training, your heart will be performing at near to its full capacity, say more than 80%. The output is also higher than simple cardio in the same amount of time. The effects of HIIT remain for hours even after the workout which helps our body to burn calories even afterward.
There are many reasons why High-Intensity Interval training is so effective and one of the main reasons is EPOC. It stands for Excess Post Oxygen Consumption (EPOC). It raises the resting body metabolism which continues to burn calories for 24 hours even after the HIIT session.
Many times one question arises or could be bothering you at the moment. So who can do HIIT workouts? Whether it is good for younger people, adults, or seniors? So the answer to these questions is HIIT is for everyone. It doesn’t matter whether you are younger or older, male or female, it is beneficial for all but you need to keep in mind certain things before doing it.
