Here, Megan Fox's (and Katy Perry's, and Lady Gaga's, and Jessica Simpson's) trainer Harley Pasternak, author of The Body Reset Diet, suggests five sex exercises that'll bring the heat between the sheets. Do 2 sets (20 reps each) of each of these moves a couple times a week, and you'll be swinging from the chandelier—or at least you'll have the strength to!
Why Harley says it's hot: "No explanation needed!"
(The thrusting speaks for itself.)
How to do it: Lay down on the ground or a mat with your head and back flat on the ground and your knees bent so that your feet are also flat on the ground, shoulder width apart and parallel. Using your abs and glutes, push your butt off the floor so that your head, hips and knees are in line. Hold for one beat and lower with control back to start. That’s one rep.
Why Harley says it's hot: "A strong core is ideal for the 'man on top.'"
How to do it: Rest your forearms on the floor and extend your legs back so your toes are on the ground and there's a straight line from your heels to your shoulders. Contract your midsection and hold as long as you can.
"Again, no explanation needed ..."
(This move works your hips, abs, core, sides, and lower back—ya know, basically all the sex muscles.)
How to do it: Start from a hands and knees position on the floor or an exercise mat, knees under hips and hands under shoulders, back flat. Bracing your abdominals, simultaneously point your right arm out straight in front and extend the left leg straight behind you. There should be a flat, level line from the tip of your fingers to your toes. Hold for 5 seconds then return to hands and knees on ground position. Maintaining stability and balance throughout your core, repeat on the other side. That’s one rep.

Why Harley says it's hot: "Skater lunges give you strong glutes—and make your butt look amazing."
How to do it: Cross your right leg behind your left leg as you bend your left knee into a half-squat position. Extend your left arm out to the side, and swing your right arm across your hips. Hop a few feet directly to the right, switching the position of your legs and arms. That's one rep. Continue hopping from side to side, without pausing or resetting your feet.
Bent-Over Reverse Flys
Why Harley says it's hot: "They sculpt a strong, sexy back."
How to do it: Stand with your feet shoulder-width apart, holding 3-5 lb. weights. Stick your butt out and lean forward until your upper torso is parallel to the floor. Raise your hands out at your sides. (Imagine you're flying away – think of your arms as wings.) Stop when your arms are parallel to the floor, then slowly lower your arms back down toward your sides. Keep a slight bend in your elbows throughout the exercise and squeeze your shoulder blades together at the top of the movement.
