When exercise drops off your to-do list, it can be a costly omission. In addition to helping beat stress, “regular exercise strengthens your immune system and boosts your mood, both of which can reduce your risk for colds, flu and more,” says Richard Kratche, MD, medical director for the Cleveland Clinic’s Twinsburg Family Health and Surgery Center.

Even bigger, it can prevent, delay or improve conditions and diseases like diabetes, high blood pressure, heart disease and arthritis. So those treadmill sessions can trim your thighs and your budget—of prescription co-pays, doctor bills and hospital visits. And workouts can help you be a healthier, calmer parent: priceless.

Add bits of exercise throughout your day. Take the stairs. Do wall push-ups in the restroom or break room. Squeeze and hold your ab muscles while sitting at your computer or run or walk outside.
