This classic from the archives never gets boring! If you're looking to test your fitness and stamina and get a bit – or maybe a lot! – sweaty, give this fast-paced power yoga practice a try!

This energetic class comes from Larry Schultz, David's first yoga teacher in San Francisco. It's called The Rocket because it "gets you there faster" and is a blended mish-mash of the Ashtanga Yoga Primary and Secondary series. Expect arm balances, hip openers, balance poses, backbends and inversions. 

Props: a towel, to mop your brow!
