he FITT Principle is the most basic rule of thumb used to guarantee your workout plan matches both your experience and your goals. So before you can put it into practice, you need to define both of those things.
1. What is your current fitness level? Are you a beginner, intermediate, or advanced exerciser?
2. What do you want to achieve in the next six to 12 months in terms of your speed, muscle tone, endurance, strength, weight, and overall fitness level?
Once you’ve outlined your specific objectives and experience, find a workout routine you’d like to try (on the Internet, in a book or magazine, or from a fitness professional), and then it's time to apply the FITT Principal to perfectly tailor the plan to fit your needs.
