PRIVATE BY DESIGN No account, no sign-up. Your sessions are stored on your device, and ThirtyThirty does not collect your data. WHY THE DEEP SQUAT? Hours of sitting at a desk, in the car or on the sofa can leave your hips and ankles feeling stiff. Resting in a deep squat, known in yoga as malasana or garland pose, is a simple, equipment-free way to break up sitting and spend time on comfortable hip and ankle mobility. Squat only as deep as is comfortable, put something under your heels if you need support, and stand up if you feel pain. If you have an injury or a medical condition, talk to a qualified healthcare professional before you start.
