The FITT principle is an exercise guide that can help people determine how long and how hard they should exercise. Every person is different and how they should exercise may depend on their age, sex, and current fitness level.
FITT is an acronym that stands for the four components of fitness:
Frequency - for example, someone can exercise every day, and someone else twice a week.
Intensity - jogging is a low-intensity cardio exercise, while there are high-intensity (HIIT) exercises as well.
Time - e.g. someone may exercise 30 or 60 minutes a day
Type - you could do cardio, strength training, or the combination of two.
