I have been practicing yoga for over 25 years, from traditional classes coming from the ancient indian traditions to the most flowy modern sequences. Something that one struggles to find, however, is teachers who are able to properly combine the best of both the ancient and the modern trends, and I found that Heather, the owner, is able to create this balance between the two which is so unique.
I have tried both her beach yoga and SUP yoga classes. She has a foundation of Sivananda yoga that she combines with great mastery into a Vinyasa sequence. The result is a deep practice that one could call both invigorating and restorative.
The beach yoga class is a little gem still to discover by many people, where you can start the day touching the still cool sand and listening to the waves breaking as if you could synchronize them with your breathing while flowing through the class. As much as some yoga teachers have great playlists and some studios have beautiful spaces they cannot compare with this beach scenario.
If the practice of asana and yoga is not new to you, I highly recommend trying both classes in a row: start the day with the beach class, which will be meditative and an intense warm up, and then play and challenge yourself trying a similar sequence on the paddleboard.
I travel to Oahu often and always visit Balanced Bliss. Have always practiced with Heather but some friends have tried some of her other teachers and they say they had a really inspiring time as well. If you live in Waikiki and don't go there regularly you are totally missing out.
