When you think of water aerobics, you probably don't imagine a Beyoncé dance party, but that's exactly what people got when they signed up for this instructor's class. Facebook user Beckyboo Wells took to social media to share this incredible video of a fierce instructor's water aerobics session [2] at Hotel Condesa De La Bahia in Alcudia, Spain. As soon as "Single Ladies" starts playing, the teacher goes all out, looking like he's ready to hit the stage with Queen Bey herself. Several of his moves come straight from the music video, but some of them seem sort of difficult to pull off in the water — like, say, the splits? In any case, check out the hilarious clip above, then see Ansel Elgort dance through the decades [3] and watch this 8-year-old's impressive moves [4] at a Zumba convention.
