When implementing the principles of training; Overload, Progression, and Specificity, using F.I.T.T. is a practical way to apply these principles. Match the exercise with the appropriate application of the F.I.T.T. principles:

frequency, intensity, time, type,

Holding yoga poses for one minute each to increase flexibility and endurance
doing cardiovascular exercises three times per week
doing resistance training exercises 3 times per week to increase muscle strength
practicing yoga for flexibility and relaxation
performing specific exercises targeting weak muscle groups
Switching from low to high intensity intervals during interval training
increasing the duration of a workout session from 30 to 45 minutes gradually over a few weeks
adjusting resistance levels on a stationary bike to maintain a challenging workout
