Power up your walk

This will help strengthen your core.

You can easily slip in a little core conditioning while you are walking.

Take a deep inhalation, then, with a strong exhalation, pull in your navel toward your spine, hold for a count of 5 and release. Do this ten times while you are walking, take a short rest, and do two more sets. Remember though to keep your shoulders back and relaxed down when you pull in your navel and try to also keep your lower back relaxed and released down and long.
