YogaSphere is a system of yoga straps co-founded by Holly Bennett, a yoga teacher from North Carolina. Bennett felt that fiddling with a standard issue yoga strap (the kind with a buckle) was disruptive during flow yoga classes. She came up with the idea of instead using several circular straps in fixed sizes. She also found that using these straps improved her students’ alignment more than a standard strap. The YogaSphere straps come in five sizes, which may be purchased individually or as a set.
