I've always hated running, but I started jogging on the treadmill. Now I love it! AND I've lost 6 lbs since I began 2 weeks ago! So challenge yourself with something you think you won't like. You may surprise yourself. I sure did!
Jillian Michaels said on the Biggest Loser to vary your caloric intake: eat on the low end for two days, eat in the middle range for three days, eat on the high end (even going a little over) on two days. This keeps your body guessing. I did this all last week and lost 3.5 lbs!
Engage your abs when walking, running, or climbing stairs. This will automatically take pressure off your knees. The exercise will be easier AND you'll burn more calories!
Many people play drinking games with alcohol. I play them with water! In the car take a drink of water after each song on the radio, watching tv take several drinks during each commercial break, at work take a drink after answering each phone call or email. 8 cups will be gone before you know it!
