The recommended frequency for aerobic activity according to the FITT Principle is:

The recommended frequency for aerobic activity according to the FITT Principle is 3-5 days a week. This recommendation is grounded in research indicating that regular aerobic exercise provides considerable health benefits, including improved cardiovascular fitness, better metabolic health, and enhanced mood.

Exercising on 3-5 days each week strikes a balance between providing sufficient stimulus for adaptation and allowing time for recovery. This frequency helps ensure individuals can build endurance, maintain weight, and reduce the risk of chronic diseases effectively. Additionally, this range supports both beginners and more conditioned individuals by allowing for flexibility in exercise programming.

Engaging in aerobic activity at this frequency promotes consistent physical engagement while minimizing the likelihood of overtraining, which can occur with daily exercise without proper recovery.
