Habitual endurance running significantly improves key biomedical health indices in physically inactive adults, specifically reducing body mass, body fat, resting heart rate, and triglycerides, while increasing VO2max and HDL cholesterol.

If you are currently inactive but healthy, starting a running routine of about 3-4 sessions per week, totaling roughly 2.3 hours, at a moderate intensity (60-90% of your max heart rate) will significantly improve your health. Over a year, you can expect to lose about 3.3 kg of body mass, reduce body fat, lower your resting heart rate, and improve your cardiovascular fitness (VO2max) and healthy cholesterol levels (HDL). You do not need to combine this with strict dieting to see these independent benefits.
