Twisting Extended Triangle
To do the Twisting Extended Triangle, you will set up in a wide stance with your feet just a little bit wider than shoulder-width. Both feet will be pointing straight ahead with the back toe only slightly turned out (although your feet can be closer to perpendicular if your mobility allows).
Then keeping your legs straight, hinge at the hips as you push your butt back, dropping the opposite hand from the leg forward down to the ground at about your instep.
Reach your other hand up toward the ceiling and rotate your chest open toward the front leg.
If you can’t reach the ground and keep your legs straight, you will want to place your hand up on a block or chair. Try to really open your chest up toward the ceiling.
