Why are high-intensity exercises like CrossFit and HIIT beneficial?

High-intensity workouts are becoming increasingly popular as people seek to improve their strength, fitness, and mental health.

HIIT (high-intensity interval training), boot camps, and CrossFit were all popular in India a few years ago. It is not by chance that these three schools of thought achieved success almost simultaneously.

Similarly, something similar had occurred in the West, and the pattern was simply repeating itself in India. And the explanation for this is simple: all three are essentially the same type of fitness routine, despite differences in branding, equipment, and programming. The essential ideas are the same for all three.

All three are improved versions of interval training in which a period of intense exercise is followed by a period of easy or relaxed exercise or recovery. This cycle is repeated for a set number of rounds or repetitions.

The intervals of vigorous activity in all three entail pretty intense to extremely intense exercise, and the sessions are quite brief, with the full session lasting 60 minutes or fewer from warm-up to cool-down.
