I tried — and failed — to lose weight many times. My wife suggested that we do a couples challenge and we put $5,000 on the line for the winner.

After years of yo-yo dieting, a challenge with my wife (not pictured) proved to be the push I needed to succeed.

• My wife and I have both struggled with weight loss over the years.
• We decided to put $5,000 on the line. The money going to the person who lost the most in 3 months.
• One of us dropped 21 pounds and was able to buy the car they always wanted.

Weight loss is one of those things that has put me on a constant rollercoaster throughout my life.
