The Twisted Triangle a hard pose to hold and there is a lot going on just remember your head position the easiest way to hold your balance is look at the floor. I always find that if you are unable to get to the floor use your block as you then have something to push against to aid the twist. Take the right leg back so both feet are pointing forward and back heel is on the floor and square the hips. Both arms out to the side level with the shoulders palms facing to the ceiling. Bring the right arm to the front left arm back again be aware of your hips try to keep facing forward so the twist is coming from the upper body. As you breath out lower the right arm to the outside of the left leg and if unable to touch floor use your block. Push against block/floor to twist and open up the chest and the top arm palm facing the same way as chest again do not twist by dropping the hips.
