Exercising Muscle Groups

A research study published in PLOS, by scientists at the University of Quebec, finds that sexual activity may be a significant form of exercise. In addition to burning calories, different muscles groups are used during sex. Certain sex positions work your abs, glutes, quadriceps, biceps, triceps, hamstrings and calves.

Burning More Calories

Sexual intercourse can last anywhere from two minutes to an hour. The longer intercourse lasts, the more calories you burn. If a 150 pound person has sex for five minutes, he burns 24 calories. If the same person has sex for 45 minutes, he burns 216 calories.

Stretching Out Foreplay

Foreplay burns fewer calories. A 150 pound person burns 25 calories in 15 minutes of foreplay. The same person would burn 216 calories in 45 minutes of foreplay. Stretching out foreplay helps burn more calories.
