I was on Instagram one day like 6 months ago and saw this aerial yoga swing advertised...I bought it!
The yoga swing I have is an off brand of the more popular Yoga Trapeze. You can do so many amazing things on it! The stretching is unbelievable. Hanging upside down elongates your whole back and spine. You can also do all kinds of strength stuff pulling you body up down sideways and backwards! Only drawback is that it's bolted in our living room and looks like a sex swing when we have guests over. Whatever. Maybe it's a multi-use?! Ha. :)
