This is one of a series of three tutorials that teaches how to activate the three “bandhas,” meaning locks or binds in Sanskrit, which form a “great lock” or “Maha Bandha” when all three are engaged which help to control and harness the flow of energy through the body. This tutorial focuses specifically on “Uddiyana Bandha,” the abdominal lock which is particularly helpful for stability through the spine when performing back and side bends.
