Get Ready to Get Frisky — These Sex Positions Will Give You the Best Workout

We have sex because it's fun, but it's also a serious workout that can really burn major calories. "The University of Montreal conducted a study that determined that, on average, men burned 100 calories from sex and women burned 69. That's roughly equivalent to a mile run," said Antonia Hall, MA., a psychologist, relationship expert, and sexpert and the award-winning author of The Ultimate Guide to a Multi-Orgasmic Life. But the body burns more calories when large muscle groups are used, so these are the positions you should go for serious results.

Planked Missionary

You're basically planking over your partner, with buttocks and back taut while also thrusting. The use of so many large muscle groups will have you burning off those extra calories in no time.

With her partner seated at the end of the bed or other pieces of furniture, she squats down onto him, really focusing on her upper thighs and keeping her back tight. "This also allows for great G-spot and A-spot stimulation so she can get a workout and full-body orgasms too," Hall said.

He is standing with her in his arms, holding her buttocks, and her legs are wrapped around him. "This will really work his major leg groups and his core, and surprisingly her core, as well. She can also brace her arms against a wall to help with thrusting," Hall said. You'll orgasmically burn those calories together!

This position requires some serious core strength, but get ready, it's worth it. "A Kama Sutra position, start by lying flat on your back," explained Bethany Ricciardi, one of TooTimid's sexexperts. This challenging position then has you prop your lower back up and use your hands to support your lower back while lifting your legs and backside way, way, way up so that they are as perpendicular to the ground as you can get them. "You might feel like you're balancing on your shoulders, that's how up you want to go! Let your man kneel before you, grab your angles, and bring his knees close in, toward your shoulders. Ask him to hold your hips to help keep you both steady! Definitely don't be afraid to also hold his thighs for leverage; you're going to be using a lot of strength and balance here. But enjoy the upside-down fun!" Ricciardi said.

Throne

This is when the guy takes a seat on the edge of the bed and the woman takes a seat on his lap facing away from him (ideally with a table or chair within arm's reach for stabilizing). "When penetration starts, it's really just quad and core work that's controlling the movement on the woman's part; the guy is motionless," explained Valerie August, a UK-based escort and dominatrix. As long as the mattress isn't too hard or high, the woman can get a kind of bounce going if she picks up speed, which is intense on the muscles but creates better stimulation (otherwise lots of slow insertions and withdrawals). "If the mattress poses an issue, you can modify the whole thing by reverting to reverse cowgirl, but with knees up and feet on the mattress — like a deep squat. Again ideally, you want a hand on a bedpost, and then thrusting is all quads, and a bit faster to activate the bouncier, shallower thrusts is key for nicer-feeling stimulation," August said.

She begins on her back, with him on his knees between her legs. "She lifts up into a backbend, which he can help support by holding her upper thighs or buttocks. Even the best personal trainer can't get you burning these many calories, and it'll be far more fun. But if it gets to be too much, she can lower herself onto her elbows," Hall said.

With both people standing, she lowers herself into Downward Dog position, hands flat on the floor. "She gets on her toes and rocks back and forth on her feet while thrusting with her major leg muscle groups. She can also raise one leg behind her, wrapping it around his waist area, which he helps support. He'll use his legs to help thrust and keep his back tight while supporting her weight. This balancing act will keep them both in shape and glowing with satisfaction!" Hall said. (This is best done standing on the floor, as we know people who have broken beds doing it!)
