Take a deep inhalation that fills up your belly and then suck your stomach in and up as you exhale. Hold for 60 seconds, breathing through your nose. Do three sets of 15 each.

Step 2
Squeeze your butt cheeks together and hold to the count of 10. Do three sets of 15 each.

Draw in your belly button as you work your pelvic muscles.

Step 4
Put both hands on the steering wheel and gently push it away from you, keeping your elbows slightly bent so you don't lock your joints. Do three sets of 10 each.

Keep turkey neck at bay by trying to reach your nose with your tongue. Do five sets of 10 repetitions.
