Want to improve the quality of your sex life—or just have better luck getting in the mood? Start with fitness! Our experts share the moves they recommend most for ramping things up in the bedroom.

Squats

You already know this move as a terrific leg and butt toner, but did you know that it can also get the blood flowing to the places that may energize your libido? "Sometimes your heart might be there, but you don't feel anything in the 'southern hemisphere,'" explains Debbie Mandel, MA, a stress and fitness expert and the author of Addicted to Stress: A Woman's 7-Step Program to Reclaim Joy and Spontaneity in Life. "Many women need a little physical help with arousal to get blood flowing to the genitalia." She suggests squats. With your feet spread shoulder-width apart, "make sure your heels stay on the floor as you 'sit' on an imaginary chair," she explains. "The lower you squat, the more you recruit your glutes and reap the benefits. Push off from your heels and hold your abdominals in tightly [as you return to standing position]." Do them slowly, aiming for 15 to 30 reps. Photo: Cavan Images/Getty Images

Happy Baby Pose

Limberness goes hand in hand with great sex—after all, who wants to deal with aching legs or a stiff lower back while in the heat of the moment? That's why Marta Montenegro, MF, MS, CSCS, NSCA-CPT, a fitness expert and the creator of the fitness DVD series Montenegro Method, suggests certain stretches to prepare you for agility between the sheets. "One of the most common reasons for lower back pain is tight hamstrings and hip flexors," she says. "Also, after spending eight hours asleep, there is a natural inflammation of the spinal discs due to the increase of the homeostatic pressure."

The happy baby pose to the rescue! "It will stretch the spine while loosening up the adductor muscles and the hamstrings, which are heavily compromised in traditional positions such as the missionary," she says. Lie on your back with your knees bent toward your chest. Grasp the outside of each foot with your hands, allowing the knees to drop down toward the floor. Align your ankles with your knees so that the shins are perpendicular to the floor. Apply downward pressure with your hands to encourage deeper opening. You can allow the tailbone to curl up off the floor slightly to decompress the lower back. Hold the pose for three to five minutes. Photo: Thinkstock

Pelvic Tilts

Want a move that will strengthen the muscles you use most during intercourse? Try the pelvic tilt. "Women tend to suffer from lower back pain, and this sometimes affects sexual positions as well as desire," says Mandel. "Pelvic tilts give you a bonus of core strength and strengthening the lower back." Lie on your back with knees bent and feet flat on the floor, shoulder-width apart. Raise your pelvic region in a straight line like a bridge. Hold your abdominals in while you tighten your glutes and push your inner thighs toward each other. Slowly lower to the floor and repeat, 20 to 25 reps, if possible.
