The FITT principle was developed by Dr. Pescatello while she served as an Associate Editor for the 8th edition of the American College of Sports Medicine Guidelines for Exercise Testing and Prescription. The FITT principle stands for frequency, intensity, time, and type, and it is the framework for designing personalized, effective, and safe exercise programs that optimize the resultant health benefits. Here’s a breakdown of these four key elements:
Application Deadlines
Summer Deadline: May 4
Fall Deadline: July 20
Frequency
This refers to how often you perform your exercise routine. When determining frequency, it is important to consider your fitness level, goals, and recovery time, among other considerations. Beginners might start with 1 to 2 to 3 sessions per week, while experienced individuals can perform exercises more often.
Intensity
This refers to how hard you push yourself during your workout. Intensity can be measured in various ways, such as your heart rate, perceived exertion (how hard you feel you're working), or the weight or resistance you are lifting or pushing. Beginners should start with light to moderate intensity and gradually increase it as they get fitter.
Time
This refers to the duration of your exercise session, including your workout period and warm-up and cool-down. The optimal time will depend on your fitness level, goals, and the type of exercise you are doing, among other considerations. Beginners might start with shorter workouts (10 to 20 to 30 minutes) that can be accumulated or continuous and gradually increased in time.
Type
This refers to the type of exercise you perform. There are various types of exercise, including aerobic and endurance, strength and resistance, flexibility, balance, and functional exercise. A well-rounded program incorporates different types of exercise to target various aspects of health and fitness.
By adjusting the four FITT components of an exercise prescription, you can create a personalized exercise program that is safe, effective, and helps you achieve your health and fitness goals.
Here are some additional points to consider:
- Progression: It is essential to gradually increase the FITT components over time to continually challenge yourself and achieve sustained results.
- Rest and Recovery: Do not forget to schedule rest days for your body to recover and prevent injuries.
- Listen to Your Body: Pay attention to how you feel during and after exercise. Adjust the FITT components if you experience pain or excessive fatigue.
One of the best things you can do is consult a healthcare professional, exercise physiologist, or certified personal trainer to design a safe and effective exercise program tailored to your needs.
