What we’ve suspected all along has been proven by science: Not only is fitness more fun with friends—it builds friendships, as well. Plus, when you exercise with people you enjoy, you’re even more likely to reach your fitness goals.

Todd A. Astornio, assistant professor of kinesiology at California State University San Marcos (CSUSM) suggests that instead of going out for lunch, join a friend for a game of tennis or an aerobics class—or go for a romantic after-dinner stroll with your spouse. What better way to share time and improve your health and fitness together? It’s a great way to achieve long-term weight loss.
