Exercises That Make You Better At Sex

Sure, you're sitting down for this position, but that doesn't mean you can take a break. "The Face Off allows for close contact between you and your partner, but a lot of men report back pain from the strain of their partner sitting on their laps," Britton says. 

Why? This move takes an incredible amount of hip flexor and core strength to perform a thrusting motion while you're seated. "If your hip flexors and abs aren't strong enough, your posture will slip, causing your belly to protrude and your lower back to round," says Gaddour. But you can build the core and hip strength necessary to hold the position with the V-sit. "It puts you in a similar position as the Face Off with your feet elevated, making you a powerhouse when your legs are actually resting on the bed or floor," he says. 

Here's how to do it: Sit on the floor. Lean back, and lift your legs off the floor so they're straight and at a 45-degree angle. You body should form a "V." Hold this position for 60 seconds. Make the position easier by bending your knees.
