With typical German meticulousness, specialists from the Academy for Healthy Living in Reidelberg decided to determine which intimate play position is best for weight loss.
As it turns out, for this purpose, lovers prefer to have sex standing up.
This kind of intimacy is equivalent to a whole hour of training with dumbbells.
To prove this, German experts invited 480 couples to participate in an experiment, who indulged in sexual pleasures daily in certain, pre-agreed positions.
Those women who made love in a vertical position lost three to five kilograms in two weeks.
And this despite the fact that they did not change their diet and generally continued to lead the same lifestyle.
“The secret is simple: this position expends more energy than other common positions,” explained study leader Dr. Hans Rosenthal. “It burns the most calories, as both partners have to expend more energy on body movement. And the woman moves much more actively than, for example, in the 'man on top' position.”
