Why You Should Practise TrikonasanaTriangle pose is a foundational standing yoga pose; once you get familiar with trikonasana it will help you with more challenging standing poses, deep hip openers and intense hamstring stretch like forward folds.
you have a look at images of trikonasana, you will see there are A LOT of variations: hips stacked on top of each other, top hip rolling in, hand on the floor, hand on the shin, fingers hooking the big toe (hi, Ashtanga!), legs really wide, legs sort of close
The intention of the pose is to strengthen and lengthen the entire back and side of the body, so explore different widths with your feet and arm positions until you feel strong, open and can breathe freely and deeply.
Triangle pose can go pretty much anywhere in a standing sequence, but because it opens up the body so nicely, I like it as one of the first poses after warming up with some sun salutations.
