If you jogged a mile and it took 15 minutes, then your “time” is 15 minutes. However, you can still use heart rate and manipulating your rest periods between exercises to increase intensity.įor cardio, time may be the most straightforward component to explain it is the length of time you are exercising. For strength training, the actual weight you’re using is the most common way of modifying intensity. Another example would be to use inclines on a treadmill or resistance on an elliptical as the intensity measurement. Cardio can use many different measurement tools, such as heart rate or 1-10 scales. For example, if you did squats on Monday, pushups on Tuesday, leg press on Thursday, and pullups on Friday, then you had a frequency of two days per week for both your upper and lower body for a total of four days of strength training.


The same can be applied to strength training, but we usually use body parts to separate it out. For example, if you jogged on Monday, swam on Tuesday, and attended a spin class on Saturday, then your “frequency” for cardio is three days for this week. F.I.T.T.įrequency refers to the number of days per week that you complete the given modality of exercise.

This principle is taught to future personal trainers, exercise specialists, and exercise physiologists as a way to adjust a client’s workouts incrementally to achieve consistent progression without overloading the client in one area. The FITT principle is a lesser-known phrase that is used to prescribe fitness and exercise recommendations to clients.
