Research shows that an exercise program, along with other healthy activities like eating well, getting plenty of rest, and stopping smoking, appears to have a positive effect on sexuality for people of all ages. So if you're a walker, you may want to add a little spring to your step. No one knows exactly, but researchers speculate that there are several reasons. Exercise improves your overall health, and that promotes better functioning of all of the body's systems. Because sex is a whole-body experience, it makes sense that you'll enjoy it more if you keep your muscles, blood vessels, and nerves performing at peak levels.
Fit people are less likely to tire during sex.
Improved muscle tone may heighten sexual pleasure, because orgasms depend on muscle activity. Sex is as much mental as it is physical, and exercise's benefits can work at an emotional level, too. Feeling healthier and more toned can raise your self-esteem and make you feel more attractive. Given the allure of exercise, it's easy to see why some people might go to extremes to maximize the benefits. The harmful effects of overexercising can be physical, too.
