How often should a person run? I want to drop my bf% about 2-3% and running is my cardio of choice. However, there is so much discerning information out there about appropriate recovery/rest times ect..Currently I run 5-7 days per week for approximately 3-5 miles and do not want to hurt myself...I do tolerate it without any injuries(with the exception of muscle fatigue/soreness) thus far, but as the mileage increases, the fear of injury keeps creeping in!! Any thoughts?
