A general guideline suggests 3-5 days of exercise per week, balancing cardiovascular and strength training. Observing energy levels and performance can help individuals adjust the frequency. It's crucial to establish a routine that allows for proper rest while still providing consistent challenges to the body. Consulting a fitness professional can ensure personalized recommendations that align with individual needs and goals, leading to sustainable progress.
