What does the 'Time' in the FITT principle refer to?

The 'Time' in the FITT principle specifically refers to the duration of the exercise performed during a workout session. It emphasizes how long an individual engages in physical activity, which is essential for achieving fitness goals. Duration can vary significantly depending on the type of exercise, the intensity, and fitness objectives. For instance, someone training for endurance may require longer sessions, while someone focusing on high-intensity training might work out for shorter periods, but with a more concentrated effort. This aspect of the FITT principle helps individuals tailor their workout plans to ensure they are exercising for an adequate amount of time to lead to improvements in fitness levels and overall health.
