Yes, but be your own best judge of managing fatigue. If you are accustomed to a certain number of total exercise sessions per week, it is not recommended that you increase your total number of exercise sessions per week by more than 1 or 2 per month. For example, if you currently exercise 5 days per week, and purchased a 3-day-per-week beginner plan, we recommend to reducing the other training you’re currently doing by at least one session, if not two or three sessions, per week, so that your total session number weekly stays at 5, 6, or 7 sessions for the first month of using the endurance training program.
