Is HIT only reserved for elite endurance athletes and individuals who already have a high level of cardiorespiratory fitness, or can HIT be modified and utilized in the general population?

People who utilizes the progression principle will ensure their exercise program increases in frequency, intensity, time, and type. the changes need to happen gradually in order to ensure they make gains in their fitness program. a person who doesn't utilize the progression principle can still gain health benefits from exercising, but will not continue to improve in cardiovascular fitness.

The answer is true atleast i think

Anice cardio work out.
