Sex is a great way to keep fit, the more you experiment, the more exercises you do during intercourse. The woman stands straight, legs wider than shoulder width and she fully bends upside down, holding the elbows in front of her and resting them on the floor if possible. The man is behind her back, slightly bends his knees, puts his arms on her lower back and penetrates his female partner. Depending on the height of the man, he can be on his toes or just stand still, in the process the couple can hold the position they like.
