The Ashtanga Primary series is the simplest, toughest and most badass of all vinyasa practices. No fancy bullshit, just raw, stripped-down vinyasa yoga. THAT UJJAI BREATH THO. In this two-hour lab session, Be will lead a Primary-inspired practice with 5 sun As, 5 sun Bs and all the Be Shakti-style 90s boombox infusion you can handle. No experience required; no wimps, please.
