Sure, the calorie burn may be small, but the reward gains will be so swole. Remember: Regular gym rules still apply, so when you’re done, wipe that shit down!
1. The Wild Pony
Lie on your stomach over a large exercise ball and place your hands on the floor. Then, get your partner to enter you from behind from a standing position. (If there’s a height issue, he can bend his knees or lift your legs wheelbarrow-style to get him where he needs to be.) See if you can get a sexy, back-and-forth rhythm going—just don’t be surprised when the ball throws in a few unexpected moves of its own.
2. The Dive Bar
Try hanging from a chin-up bar suspended in a door frame, then wrap your legs around his hips. Rock back and forth against him while he uses his own upper-body strength to hold you up. This is not good for leisurely sex unless you happen to have mega stamina. But it is pretty impressive for an urgent quickie.
3. The Treadmill Split
Hop up onto the treadmill (which should be unplugged and preferably steadily placed against a wall), and put a leg over each arm rest so your pelvis is suspended in air. Then, get him to slide into you like he would an easy jog on this thing. To help you both maintain your balance, get him to grab and hold on to your butt, pulling you in closer as you thrust for distance.
4. The Anti-Gravity Ball
In this position, lie back onto a large yoga ball, putting your legs over his shoulders. Let your head fall back and arms go limp on the floor as you enjoy an amazing session of weightless oral. He will be in charge of keeping you steady—and enjoy a killer view.
