Vinyasa yoga includes a lot of poses with the arms reaching overhead, but fully elevating the arms can trigger shoulder discomfort for many students. This practice eliminates any postures that elevate the arms beyond 90 degrees, while still being strong and dynamic. Jump right in with core work, flow through sun salutations, then challenge your strength with locust, boat and forearm planks. You'll get the powerful flow you're after while keeping shoulder tension at bay.
