Crouching Tiger, Aroused Dragon

Both partners will quickly realize why the Crouching Tiger has great pleasure and orgasm potential. In this position, the woman does a sexy squat above the man.The woman can then supports herself by putting her hands anywhere on his body for support and then move herself up and down. In terms of muscle tone, this position will work her inner thigh and calf muscles. Meanwhile, to get a better view, the man should lift his head and contract his stomach muscles. Maintaining this position as long as possible will give his abdomen a hard workout. He should feel the tension and clench tighter as it starts to burn. He can even reach forward and caress his partner's body and add to everyone's pleasure.

Down Doggy! Good Doggy!

This erotic, animalistic position is very similar to the usual doggy style, with a few slight changes. After the man enters from behind, as in the regular doggy position, the woman leans down and supports her weight on her elbows, while the man lifts one bent leg forward, rather than kneeling on both knees. The woman will feel the tension in her triceps while making love in this position and the man will work his thighs when his leg stays raised. He should switch legs halfway through to hit give both legs a work out.

Humpty Bumpty

In this position, the man is sitting up while the woman is sitting on him with her legs raised in the air in a straddle. She holds onto his neck with her hands while he moves her back and forth. This will work the woman's arms, stomach and legs. The man will tone his arms while moving the woman's body, and will strengthen his legs from the support he is providing to his partner.

Wheelbarrow of Fun

The woman lies on her stomach on the bed with her legs slightly open and her knees slightly off the edge. The man stands behind her at the end of her bed and lifts her legs up toward him, until he is able to enter from behind. The woman then bends her legs and wraps them around him, locking her feet together at the ankles, while the man holds her with his hands and rests her on his thighs. This will tone the triceps and lower back. You can also try this on the floor. If you're really talented, you can try walking around the room while in this position and think back to your days in summer camp during color war.

Let's Get Crazy

This position is a great workout for the woman's stomach and buttocks. While lying on her back, the woman extends her legs straight in the air, slightly spread, with her rear lifted off the ground. The man bends down in a slight squat to enter her, working his quads, and when using his arms for support, he works his triceps.
