Triangle pose: the short version
For her first few years of yoga, Chris Lalor thought a pose was something you got into and then held, like a photograph. She was a bull at a gate, stiff as a board, waiting for the teacher to say “come up”. Then a teacher told her to press the outer edge of her back heel down in triangle pose (Utthita Trikonasana), and asked what happened. Her whole leg woke up, and she hadn’t moved. This note shows how to set up Triangle, how a block or a chair makes it work, and why that one heel changes the pose. It sits in our poses and practice notes, and in our flexibility and stiffness notes.
Iyengar yoga is the style developed by Mr BKS Iyengar. In the 20th century he did more than anyone to set down traditional Indian yoga, through his books and his teaching, and he pioneered the use of props. It is sometimes called modern classical yoga, and it’s the style we teach at Flametree.
Triangle pose in short form
- The set-up: feet wide, front foot turned out, back foot slightly in, both legs straight.
- The reach: trunk extends sideways over the front leg, and the top arm goes straight up.
- Props: a block under the lower hand, or a chair, lets you keep the legs straight and the chest open.
- The heel: press the outer edge of the back heel down, and the whole leg wakes up.
- Not a photograph: a pose is something you keep doing, every second you are in it.
- Next step: your first class is free if you’re new to Flametree.
How do you do triangle pose?
Stand wide, keep both legs straight, and reach sideways over the front leg. The points to look for are:
- Feet wide apart. Turn the front foot out and the back foot slightly in.
- Both legs straight. A bent front knee turns Triangle into a different pose, Extended Side Angle.
- Reach sideways. Extend the trunk over the front leg. Don’t drop it forward.
- Lower hand on the shin, the ankle, a block, a chair or the floor beside the front foot.
- Top arm straight up, in one line with the lower arm.
- Chest facing forward, and your head turned to look up at the top hand.
Chris has practised Triangle for decades, and says she is still learning more about it. At the start it looked nothing like the photos. So don’t worry if yours doesn’t yet.

Why does triangle pose feel so hard?
Because the legs are straight and the hips, hamstrings and sides all have to open. (The hamstrings are the muscles at the back of your thighs.) Many people respond by bending the front leg or folding forward over it. That collapses the chest.
Chris’s advice is to avoid folding forward in a way that contracts the chest and lungs. Keep the legs straight, and raise the hand instead. It’s better to hold the block higher, or put your hand higher on the shin, than to bend the front leg or collapse the chest.
How do a block or a chair help in triangle pose?
They bring the floor up to your hand. This is the beginner version at Flametree. Here are the options:
- A block under the lower hand. Hold it higher if you need more room for the chest.
- The shin as a rest for the hand, higher up if you need more room for the chest.
- A chair, with the lower hand on the chair. This keeps the legs straight and lets the chest open.
Chris uses different hand and block positions in her videos. She says they help beginners do Triangle as an effective side stretch.

Why press the back heel in triangle pose?
Because a pose is like a tent. A tent pole stands up because the guy ropes pull on it from opposite sides. Loosen one rope and the tent sags. Your body in a pose works the same way. You press down through the feet and lift up through the spine. You reach out through the fingertips and draw the shoulder back in. Nothing is moving, and everything is working.
Try it where you stand:
- Stand with your feet about hip width apart.
- Press the outer edge of one heel firmly into the floor.
- Notice where the push travels: the ankle, shin, knee, thigh and hip.
- Now lift up through the inner leg at the same time. Down and up together.
- Feel the leg turn firm and awake, without moving.
Chris says that almost nobody finds the second direction alone. It’s what the props, the long holds and the precise instructions of Iyengar yoga are there to teach. For how a held pose builds muscle and loads bone, see how a yoga pose makes energy. For joints, see our post on yoga for arthritis.
What about revolved triangle?
Revolved Triangle Pose (Parivrtta Trikonasana) is a different pose, where the trunk twists over the front leg. Learn the plain triangle first. Our note on how to twist safely covers twisting poses.

Questions people ask
How do I do triangle pose?
Stand with your feet wide apart, the front foot turned out and the back foot slightly in. Keep both legs straight and reach sideways over the front leg. Put the lower hand on the shin, a block or a chair, and stretch the top arm straight up. Turn your head to look at the top hand.
Should my front leg be straight in triangle pose?
Yes, and that is the usual challenge. A bent front knee turns the pose into Extended Side Angle. If you can’t keep it straight, hold a block higher or put your hand higher on the shin.
Where does my bottom hand go in triangle pose?
On the shin, the ankle, a block, a chair or the floor beside the front foot. The best place is the one where you can keep both legs straight and your chest open. Higher is better than a bent knee or a collapsed chest.
What props can I use for triangle pose?
A block under the lower hand, or a chair. Both bring the floor up to your hand so you keep the legs straight and the chest facing forward. Your teacher can show you the heights.
Why press the back heel down in triangle pose?
It wakes up the whole back leg. Chris describes a push through the ankle, shin, knee, thigh and hip that also lengthens the spine. A pose is something you keep doing, like the ropes that hold a tent up.
What is the difference between triangle pose and revolved triangle?
In triangle pose the trunk extends sideways over the front leg. In revolved triangle (Parivrtta Trikonasana) the trunk twists over the front leg. They are different poses, and triangle comes first.
Is triangle pose good for beginners?
Many beginners learn it with a block or a chair. It teaches the legs, hips and chest to work together. Go to your own limit, and keep the legs straight.
