Triangle Pose step by step: find length instead of collapsing in a wide stance, protect the front knee and use block and wall. With mistake fixes.
Why does Triangle Pose feel like a contortion to many, even though it looks so simple? The honest answer: because you do three things at once that your body never combines in daily life: you spread your legs wide, lengthen the torso sideways and rotate the chest. In Triangle Pose (Utthita Trikonasana, "extended triangle") you stand with straight legs in a wide stance, the torso reaches sideways over the front leg, and the arms form a vertical line.
What happens to your hip here has been measured in 20 experienced yoga practitioners with motion analysis: Triangle takes the hip into extension and internal rotation, so it is one of the poses that bring the joint to the edges of its range [1]. For healthy hips that is normal. For you it means: quality before depth.
How hard is the pose really? Medium in execution, easy in idea. With a block and a wall you learn it cleanly in a few sessions without twisting yourself.
Place the feet 1 to 1.2 metres apart (about one leg length). The right foot turns out 90°, the left foot slightly in. The heel of the front foot points toward the middle of the back foot. Arms go out to the side at shoulder height.
Milestone: you stand stably for 5 breaths in the wide stance, the knees are soft and point over the middle toes.
Inhale and push the torso far forward to the right, as if reaching across a table edge for something. Only when you can't go further do you let the hip move back and the right hand sink down.
The right hand lands on the shin, a block or (only if the back stays long) the floor. Not on the knee. The left arm reaches to the ceiling, shoulders stacked.
Turn the chest upward without losing the pelvis. The wall helps: buttocks, shoulder blades and the back of the head touch it. The gaze goes to the upper hand or, with neck tension, straight ahead.
Milestone to move on: you hold 30 seconds with a long trunk, without the front knee locking or the ribcage collapsing.
Press the back foot into the floor and rise on an inhale, the arm staying long. Switch sides. Do two rounds per side.
In Triangle Pose the front knee is easily hyperextended, especially in people with flexible joints. A systematic review of 9,129 yoga practitioners found a higher risk of meniscus injuries (OR = 1.72) compared with non-practitioners [3], so the rule is: soft knee, don't lock it.
With hip impingement, a hip replacement, sciatica or an acute back problem, talk to your doctor or physiotherapist before practising. With dizziness or low blood pressure, come up slowly. This guide explains and motivates; it does not replace supervised training.
Practise Triangle with the wall behind you and set the back foot lightly against the wall edge: you instantly feel whether your pelvis is moving back. In addition: instead of holding, you can breathe in and out four to five times and make yourself slightly longer on each inhale. For the flexibility gain 30 seconds are enough; in one study 60 seconds brought no additional gain compared with 30 [2].
About one leg length, that is 1 to 1.2 metres, depending on height. If you stand too narrow, the weight falls forward and the torso collapses. If you stand too wide, the stance wobbles. The benchmark: you can keep the legs long and the pelvis stays over the middle.
On the shin, a block or the floor, but never on the knee joint. With a block you get, without a round back, into a position where you really lengthen sideways. The floor is not a goal but an option for very flexible people.
Only if you lock the front knee or let it tip inward. With a soft knee, a toe-knee line and a block it is usually unproblematic. With knee pain, bend the front knee slightly and use Warrior 2 as an alternative.
About 30 seconds per side, that is 5 to 8 calm breaths. A stretching study found that 30 seconds gave the full gain [2]. Rather repeat twice per side than hold one side for too long.
In Warrior 2 you bend the front knee to about 90 degrees and keep the torso upright over the pelvis. In Triangle you straighten both legs and lean the torso sideways over the front leg. Warrior 2 is the strength base, Triangle the extension. If you stand securely in Warrior 2, you are ready for Triangle.
