Parivrtta Trikonasana — Bound: A Complete Guide to Bound Revolved Triangle

Quick Intro

Parivrtta Trikonasana — Bound (Revolved Triangle — Bound Arms in English) is a yoga exercise performed from full Parivrtta Trikonasana (Revolved Triangle), threading the lower arm behind the back leg and clasping the opposite wrist or hand instead of placing that hand on the floor or a block.

Equipment Needed

No equipment is needed to perform Parivrtta Trikonasana — Bound. A yoga mat is optional and mainly adds traction under both feet through the twist.

Why Parivrtta Trikonasana — Bound Matters

The back of the front leg’s thigh (hamstrings, biceps femoris) lengthens through the unsupported hinge, and the side of the torso (obliques) drives the rotation without any floor support to lean on. The muscles along the spine (erector spinae) hold the twisted back upright, and the outer hip (gluteus medius) keeps the pelvis square against the added shoulder demand. The small muscles around the shoulder joint (rotator cuff) stabilize the bound arms, and the side of the upper back (latissimus dorsi) helps draw the threaded arm into the bind.

Flexibility is the main demand, and losing the floor support makes balance a close second.

When to Do It

Parivrtta Trikonasana — Bound works well once the floor-reaching twist feels stable, removing the hand’s floor support entirely and asking the hamstrings, hips and shoulders to hold the shape together. Most sessions built around advanced twists can add this once the standard version needs no correction.

• A floor-reaching twist that already holds steady through a full breath count. The bind removes the one point of outside support that version still relies on.
• Open shoulders from earlier poses in the same session. The bind asks the shoulder to reach further behind the back than most yoga poses require.
• Building toward more advanced bound standing poses. The bind skill and hip-squaring discipline here transfer directly to related shapes.

For most people who already hold the floor-reaching version comfortably, this is the next challenge, and it exists to test whether the hips can stay square without the floor’s help.

Getting Ready

A few rounds of shoulder openers, such as clasping the hands behind the back in a standing fold, warm the shoulders before threading the bind. Practicing the floor-reaching twist for a breath or two first confirms the base pose is ready before removing its support.

Square the hips fully to the front foot before threading the bind. Attempting the bind before the hips are square is a common cause of losing balance in this variation.

Step-by-Step Instructions

1. The stance. Set up in the wide stance with the front foot forward, hips square.

2. The hinge. Hinge forward at the hip, keeping the spine long.

3. The thread. Rotate the torso and thread the lower arm behind the back leg.

4. The bind. Reach the threaded arm around to clasp the opposite wrist or hand, extending the free arm upward if balance allows.

5. The release. Unclasp, untwist and lift back up to standing, then switch sides.

How Many, How Often

Parivrtta Trikonasana — Bound is dosed by breath count per side, since a steady breath is what keeps the bind and the hip position both stable at once.

Keeping the hips square through the whole bind matters more here than whether the hands fully connect, since a rotated hip in pursuit of the bind is exactly the strain this variation is meant to avoid.

Modifications and Variations

Parivrtta Trikonasana — Bound sits at the most demanding end of its own progression, with a clear easier step below it and nothing deeper than the bind beyond it.

For an easier entry point, Parivrtta Trikonasana rests the lower hand on the floor or a block instead of binding, keeping the same twist without the added shoulder demand.

Progression path: Parivrtta Trikonasana → Parivrtta Trikonasana — Bound

Attempt the thread without forcing a full clasp for as many sessions as it takes, since a near-bind with square hips trains the pose better than a forced full bind with rotated hips.

Common Mistakes to Avoid

Rotating the hips open to force the hands to connect. This trades the entire point of squared hips for the appearance of a completed bind. Backing off the reach until the hips stay square is the fix.

Collapsing the chest to reach further into the bind. A collapsed chest loses the long spine the twist depends on. Keeping the chest lifted, even with a shallower bind, protects the back.

Rushing the thread before the hips are square. This is the exact setup for the strain the whole pose is built to avoid. Squaring the hips fully first, every single time, before threading the arm, is non-negotiable here.

Holding the breath while attempting the bind. The combined hinge, twist and shoulder reach tempts bracing. A slow, steady breath helps the shoulder find the bind more than tensing does.

After Your Set

Standing tall and rolling both shoulders through a few slow circles releases the shoulders that just held the bind. A few gentle forward folds from standing ease the hamstrings that stretched through the unsupported hinge.

Going Deeper

This variation is usually trained by anyone who already holds the floor-reaching twist with stability, as a test of whether that stability survives without the floor’s support. The most common way it stalls isn’t shoulder flexibility, but the hips rotating open the instant the reach for the bind gets prioritized over keeping them square, which is precisely the mechanism that turns this pose into a strain risk. Squaring the hips first and treating the bind itself as optional, every single session, is what keeps this variation worth practicing.

Someone comfortable with the floor-reaching version generally manages a partial thread with square hips within the first three to five weeks, and reaches a full bind on both sides somewhere in the ten to fourteen week range.

How to Know You’re Improving

1. A square-hipped hinge with a partial thread behind the back leg
2. A 2-breath hold with the hands close to connecting, hips still square
3. A full bind held for 3 breaths on both sides
4. A smooth, controlled entry into and out of the bind without the hips rotating

Square hips through the whole attempt, not whether the hands fully connect, is what progress looks like here.

Muscles Worked

• Biceps Femoris (a muscle at the back of the thigh, stretched with no hand on the floor to share the load)
• Obliques (the muscles along the sides of the waist, holding the twist entirely through the trunk)
• Erector Spinae (the muscles running along the length of the spine, keeping the spine long once the floor support is gone)
• Gluteus Medius (a smaller glute muscle at the side of the hip, holding the front hip square through a deeper rotation)
• Rotator Cuff (the small muscle group deep at the shoulder joint, holding the bound shoulders at their end range)
• Latissimus Dorsi (a large back muscle, stretched as the arm threads behind the leg to clasp)

FAQ

Is it okay if my hands never connect in the bind? Yes, an attempt with square hips is worth more than a forced connection with rotated hips. The bind itself is not the measure of this pose.

Why does this feel so much less stable than the floor-reaching version? Removing the hand’s floor contact takes away a point of support the earlier version relies on. That reduced stability is exactly what this variation is training.

Do I need especially open shoulders to attempt this pose? Reasonably open shoulders help, but the hip-squaring discipline matters more for safety than shoulder flexibility does for completing the bind.

Can I practice the thread near a wall for extra confidence? Yes, lightly using a wall for balance while learning the thread is a reasonable way to build confidence before removing that support.
