Last December, a video featuring the bendy-flexy talents of Equinox yoga instructor Briohny Smyth defying gravity in her underwear in a bedroom went viral. 4.2 million views and 2,000 comments later ("her feet look like hands," "her ass looks amazing"), Equinox is releasing a follow-up. In the first video, Smyth's then-boyfriend Dice Iida-Klein can be seen snoozing in bed. This time around, Iida-Klein is Smyth's fiancé, and he joins her on the yoga mat. The Cut has an exclusive preview teaser of the next installment of sexy yoga. Click to watch the video which features toned tummy-touching, firm booty-balancing, and very tiny shorts. Happy Labor Day, y'all!
