In case you need an incentive to get off the couch, two new studies conclude that regular exercise can improve a man's sex life, according to a recent article in the Los Angeles Times .

This news is no surprise to Clarice Colon, a certified personal trainer with Bally Total Fitness in Fort Chester, New York. The stories she hears from her clients support the conclusions of the two studies. Previously inactive men who take up regular fitness routines say they have higher self-esteem and the spark has returned to their relationships or they're back in the dating game. Colon points out that the benefits of physical activity are not limited to men. She suggests weight training and calisthenics such as pushups, pull-ups, and dips for men or women who want to get started on a fitness regimen.
