The FITT Principle is a great way to overcome plateaus and change up your workout routines. FITT stands for Frequency / Intensity / Time / Type. Frequency: how often you exercise. Intensity: how hard you work during exercise. Time: the length of time you exercise. Type: the type of exercise you do. To continue to make progress, change up your routine by modifying two of these factors every 2-4 weeks.
