The arc is a lovely counterpart to the L, because it opens the front body and hip flexor areas, and often has the potential to strengthen the glutes and hamstrings – areas we tend to lengthen/stretch a lot in yoga.
The arc represents backbends, and like the L shape, it can be done in active or passive ways, depending on what you’re working on.
For example, a simple, supported backbend during a work break is the perfect way to counteract curling forward posture. On the other hand, an active backbend like Bow or King Cobra will engage your back body, working to strengthen and tone the area.
Backbends are a crucial part of posture maintenance and well-balanced asana practice. Find one that works for you!
