Direct answer
Triangle Pose, or Trikonasana, is a standing posture combining a wide stance, hip movement, side bending and rotation. Use a shorter stance and a block or chair beneath the lower hand. Keep both knees comfortably supported and place the lower hand where the torso can stay controlled. Touching the floor and stacking the shoulders perfectly are not requirements.
Build a dependable base
Stand with feet comfortably wide, then turn the front foot toward the short edge of the mat. Angle the back foot in a direction that lets the knee and hip feel stable. There is no single degree setting for every anatomy.
Straighten the legs without locking or pushing the knees backward. Shift the pelvis slightly toward the back leg as the torso reaches over the front leg, then place the hand on the shin, a block, chair or wall. Do not press directly on the knee joint.
Rotate the chest only as far as breathing and balance remain comfortable. The upper arm can stay at the hip rather than reaching upward. Look forward or down if turning the head affects the neck or balance.
The block is part of the architecture
A higher support reduces the need to collapse the torso or hang from the lower shoulder. Place the block inside or outside the front foot according to stability and instruction. A chair seat or wall can provide more dependable support.
If hamstring sensation dominates, bend the front knee slightly or shorten the stance. A straight-looking leg is not more advanced when it sacrifices joint control.
The [yoga flexibility guide](/journal/yoga/yoga-for-flexibility) explains why range differs by joint and person. Stronger stretching does not automatically produce better results.
Knee and hip alignment is not a photograph
Teachers often cue the front knee to point toward the toes. This can help avoid an uncontrolled collapse, but individual rotation and foot placement differ. Adjust the stance rather than forcing the hip open.
A small biomechanics study of thirteen experienced women found substantial hip contribution and measured joint demands in Triangle, Warrior II and crescent lunge. Such laboratory findings describe a small sample; they do not prescribe one safe angle for every student.
Balance and neck options
Practise near a wall and keep the gaze steady. Looking upward is optional. The [yoga balance guide](/journal/yoga/yoga-for-balance) recommends changing one difficulty variable at a time rather than narrowing the base and turning the head together.
Come out by bending the front knee slightly and pressing through the feet, or use support. Move slowly before changing sides.
Health considerations
Existing knee, hip, spine or balance conditions may need individual adaptation. Severe high blood pressure, glaucoma, pregnancy and recent surgery can also alter which orientation or range is appropriate. NCCIH recommends qualified instruction and discussion of health needs.
Stop for sharp pain, numbness, dizziness, visual symptoms or instability. Do not stay because a teacher says discomfort represents emotional release.
Claims need a whole-program view
Triangle can challenge balance, range and muscular control. Research on complete yoga programmes cannot establish that this pose alone improves digestion, cures back pain or builds bone. Use it as a posture, not a treatment claim.
Conclusion
Trikonasana is stable when the feet, support and torso work together. Shorten the stance, raise the lower hand and limit rotation until the pose feels controlled. The aim is a sustainable relationship to gravity, not a hand on the floor.
