Couples and friends that sweat together stay together. Here’s the proof. One of the most exciting (and potentially steamy) partner workouts is acro-yoga, a practice that combines the flexibility and strength of yoga with the grace of acrobatics. We featured power yoga couple Briohny Smyth and Dice Iida-Klein's stunning flow in our February issue. "When I'm flying, Dice supports me, but that doesn't mean I can relax. I have to use core strength to balance my weight and help him," Smyth says. And it goes beyond a physical connection. "We can both get so busy that we're sitting in the same room and not really connecting. Linking our bodies in a pose repairs that—it's the greatest relationship tool I've found." Consider these beautiful Instagram photos of acro-yoga poses inspiration for your weekend.
