You Down With Sexercise? Skip the Gym and Burn Major Calories in Bed Right Now

y way you slice it, sex is a workout. But you can amp up the toning and cardio—and possibly your pleasure—with a few tweaks to your usual routine. If you keep these tips in mind, you'll notice more defined abs, toned legs, a tighter tush, overall weight loss, and improved satisfaction. Uh, what's not to like?

5 ways to turn sex into a workout:

Thrust back when you're in missionary. While some might argue the whole point of man-on-top action is so you can lie back and enjoy the ride, you're missing a concentrated core workout if you don't wiggle around below. For each thrust, give your guy an equal and opposite push back and you'll feel your abs start to burn!

Squat while in woman-on-top. With this slight tweak to this orgasm-all-but-guaranteed-position, you'll burn calories and tone your buns and legs: Rather than kneeling over the top of your man, come up onto your feet—just like you would in a squat—and move up and down. Your tush will tighten within seconds!

Channel Pilates and go into a plank. Bracing yourself during doggy-style already burns calories and tones your upper arms. But you can kick it up a notch by lowering yourself into a plank position the next time your guy enters from behind. You'll engage your core and burn extra calories!

Use your hands. When it comes to burning calories, don’t discount a good ol' hand job. Vary your speed and pressure, and involve your entire body by rocking against his and making out as you go. Your man will love it, and your sore arms will thank you later.

Turn up the heat. Like, literally, adjust your thermostat, hot-yoga style. The theory behind these workouts is that higher temps lead to a sweatier workout, which burns more calories. So get it on however you like, as long as you turn up the heat.
