There are many studies that show that you can burn about 4 calories per minute during sex. But the point is not necessarily in calories, the most important thing is good feeling and mood for the day ahead. Just like exercise, during sex, our body produces endorphins, which lift our mood and can even relieve pain. To make your morning “exercise” even more enjoyable, you won’t need sportswear, but maybe a quality lubricant will come in handy?
