You can do yoga anywhere, people say, even on water. Julia, who teaches stand-up paddleboard yoga in Vienna, ascribes to this theory: "SUP yoga is the perfect combination of yoga, nature, water and summer." On one hand, it's a challenge physically (try to keep your balance!) and it engages your core muscles. On the other, it's a mental exercise in which you have to concentrate hard, "because when your thoughts wander, that's it for your balance, and you end up going headfirst into the water". Even so, Julia says that, in a group of 15, just one person on average falls into the water. Most of the participants surprise themselves, finding that SUP yoga isn't as difficult as they'd expected.
Anything can happen when you're practicing SUP yoga in the middle of nature. Alongside spots of involuntary swimming, one might sometimes encounter a group of baby swans swimming by. "No one experience is like another", say Julia. "But they all do have one thing in common: at the end of the session, the yogis return their SUP board with a smile, and say that they feel as though they've taken a break from the stresses of the everyday".
