It takes not two, but three people to tackle the Triangle Dance and people all over social media are proving they're up to the challenge. It starts with three people standing in a triangle formation with their hands on each other's shoulders. Then they each take turns jumping into the middle of each other, trying not to crash into their partners. Most people are nailing the dance, but others aren't as quick at mastering it. Teachers are joining the fun, and a trio even used the move as a pre-Zumba warm up.
