Revolved Triangle — Hand on Block

Quick Intro

Parivrtta Trikonasana — Supported (Revolved Triangle — Hand on Block in English) is a yoga exercise performed from a wide standing stance, resting the lower hand on a block placed inside or outside the front foot while the torso twists and the opposite arm reaches to the ceiling.

Equipment Needed

Parivrtta Trikonasana — Supported requires a yoga block, used under the lower hand to bring the floor up to a reachable height. A yoga mat is optional and mainly adds traction under both feet.

Why Parivrtta Trikonasana — Supported Matters

The back of the front leg’s thigh (hamstrings, biceps femoris) lengthens through the hinge, and the side of the torso (obliques) drives the rotation. The muscles along the spine (erector spinae) keep the twisted back long, helped by the block height, and the outer hip (gluteus medius) holds the pelvis square against the twist.

Flexibility is the main demand, and the narrow twisted stance adds a moderate balance test.

When to Do It

Parivrtta Trikonasana — Supported works well for anyone whose hamstrings are not yet long enough to reach the floor without rounding the spine, and it is the entry point into the full twisting pose. Most sessions that include the floor version can start here instead when the back rounds trying to reach lower.

Hamstrings not yet long enough to reach the floor with a long spine. The block removes that specific limitation while the twist and hip-squaring work stay identical.
New practitioners still learning to square the hips before adding rotation. The added height makes it easier to notice the hips drifting open.
A desire to hold the twist longer without the lower back rounding under fatigue. A stable hand height helps the spine stay long for the whole breath count.

For most people building toward the floor version, this is the more sensible entry point, and it exists to keep the spine long while the hamstrings catch up.

Getting Ready

A short warm-up of standing hamstring activation and a few gentle torso twists gets both systems ready before the pose asks for them together. Setting the block on its tallest setting to start, then trying a shallow version of the reach, previews how much height the current stretch needs.

Choose a block height that lets the spine stay fully extended through the twist. The twist should never be sacrificed for a lower hand placement.

Step-by-Step Instructions

1. The stance. Stand with the feet wide, front foot forward, and place a block on its tallest setting near the front foot.

2. The square. Square the hips toward the front foot before adding any rotation.

3. The hinge. Hinge forward at the hip, keeping the spine long, and rest the lower hand on the block.

4. The twist. Rotate the torso, extending the same-side arm to the ceiling.

5. The exit. Rotate back to center and rise to standing, then repeat on the opposite side.

How Many, How Often

Parivrtta Trikonasana — Supported is dosed by breath count per side, since a steady breath lets the twist settle without forcing the hand any lower than the block allows.

Level	Where you’re at	What to do
Beginner	New to the twist	Hold for 3 breaths per side with the block at its tallest setting.
Intermediate	The hips stay square through the hold	Hold for 5 breaths per side, lowering the block one setting once the twist feels stable.
Advanced	The lowest block height feels controlled	Extend to 5 to 8 breaths per side, testing whether the hand can leave the block for the floor version.

Keeping the hips square through the whole hold matters more here than how low the block sits, since a rotated hip undoes the entire purpose of the support.

Modifications and Variations

Parivrtta Trikonasana — Supported sits at the accessible end of its own progression, with one clear next step and no easier version below it.

For more difficulty, Parivrtta Trikonasana removes the block entirely, reaching the hand to the floor once the hamstrings and hip-squaring control allow it.

Lower the block one setting at a time across sessions, keeping the hip-squaring discipline intact at each new height before dropping any further.

Common Mistakes to Avoid

Choosing a block height that forces the hips open. This defeats the entire purpose of the support, since a too-low block just recreates the strain the block exists to prevent. Raising the block back up until the hips stay square is the fix.

Rounding the spine to reach the block instead of hinging from the hip. A rounded back trades the hinge for a shortcut. Keeping the spine long, even with the block at its tallest setting, protects the back through the twist.

Rushing to lower the block before the current height feels stable. Progress here is a height decision, not a timeline. Staying at one height until it needs no active correction is what builds toward the floor version.

Holding the breath through the twist. The combined hinge and rotation tempts bracing. A slow, steady breath helps the hips stay square more than tensing does.

After Your Set

A few relaxed side-to-side sways, arms hanging loose, unwind the torso after holding the twist. Rolling gently through the ankles and knees for a moment settles the legs that supported the hinge.

Going Deeper

This variation is usually trained by anyone whose hamstrings are not yet ready for the full floor-reaching twist, as an entry point. The most common way it stalls isn’t hamstring length, but choosing a block height low enough that the hips rotate open to compensate, which quietly trades the training effect for the appearance of more depth. Choosing the tallest workable height and staying there until it feels stable is what makes the eventual floor version reachable.

Someone new to this twist generally manages a steady 3-breath hold on both sides within the first one to two weeks, and starts lowering the block comfortably somewhere in the four to six week range.

How to Know You’re Improving

A 3-breath hold on both sides with the hips staying square at the tallest block height
A spine that stays extended through the hinge instead of rounding toward the block
A comfortable 5-breath hold with the block lowered one setting
Square hips maintained even as the block height decreases

Square hips at whatever block height is used, not how low the block sits, is what progress looks like here.

Muscles Worked

Biceps Femoris (a muscle at the back of the thigh, stretched to the depth the block height allows)
Obliques (the muscles along the sides of the waist, free to rotate further once the hand has support)
Erector Spinae (the muscles running along the length of the spine, kept long because the reach stops short of the floor)
Gluteus Medius (a smaller glute muscle at the side of the hip, holding the front hip square through the twist)

FAQ

Is the block a permanent tool, or should I aim to remove it eventually? Both are valid. Some practitioners work toward the floor version, while others use the block indefinitely and get the same training benefit either way.

Why do my hips still feel like they’re rotating open even with the block? This usually means the block is set too low for the current hamstring length. Raising it back up until the hips stay square resolves it.

Can I use a stack of books instead of a yoga block? A stable, non-sliding stack works in a pinch, though a proper block’s fixed heights make it easier to progress in controlled steps.

Is it normal for one side to need a taller block than the other? Yes, that is common. Each side can use its own height.
