Most people brush their teeth in the morning before they head out the door, and at night before they hit the hay. Use that time to add a little exercise into your day, since every little bit helps. Every time you brush your chompers, do 25 push-ups on the counter or sink. That adds up to 50 push-ups a day, and 350 push-ups a week! If your arms are stronger, do 30 or 40, or do less if you're just starting out. Push-ups are one of the most effective ways to tone your upper body, and you'll start to see results soon after adding these counter push-ups to your routine.
