Here's a pose...
…with Lane Jaffe, demo-ing.
Lane's a So Cal High School Lacrosse coach. He's also a certified yoga instructor. Every week, sometimes twice a week, he leads his team through a strong, sweaty yoga class.
A competitive Lacrosse coach teaching his team yoga.
Right here above, Lane's in side angle pose (Parsvakonasana). His heels are lined up and he's making sure his front hip is rotating outward so that he doesn't torque that knee. He's bending his front knee to a 90 degree angle and letting his back heel ditch out away from his body a bit. Then, as he's leaning to the side, he's not only stretching his side ribs, he's drawing his shoulder blades down and in - as he extends his arms apart - broadening across the collarbones. His neck is long - chin tucked- so he can look up and get deep a hip stretch and also a nice torso twist too.
Shades, aside, you can see Lane's face is calm. He's real steady about it all. It may not look like he's working. But he is.
That's another thing about yoga.
It teaches you how to work.
