What is the FITT esign for flexibility?

The FITT principle for flexibility includes Frequency, Intensity, Time, and Type. Frequency refers to how often you should stretch, ideally at least 2-3 times per week. Intensity is about how far you should stretch, aiming for a slight discomfort without pain. Time involves the duration of each stretch, typically holding for 15-30 seconds, and Type specifies the different stretching methods, such as static, dynamic, or PNF stretching.
