Bound Angle — Blocks Under Knees

Quick Intro

Supported Baddha Konasana (Bound Angle Pose — Blocks Under Knees in English) is a yoga exercise performed sitting with the soles of the feet together, sliding a block under each outer knee so the hips can rest without reaching for the floor at all.

Equipment Needed

Supported Baddha Konasana needs two yoga blocks, one under each knee (a pair of thick books or a rolled blanket works as a substitute). A yoga mat is optional and adds a little padding under the seat.

Why Supported Baddha Konasana Matters

The inner thigh (adductors) and hip flexors (iliopsoas) are the areas this pose is built around, but with the blocks taking the knees’ full weight, neither is being stretched here. The outer hip (gluteus medius) and the muscles along the spine (erector spinae) do the only work left, keeping the seated position upright and comfortable.

Flexibility is the main demand, though in this supported version it describes the shape itself and not any active stretching sensation.

When to Do It

Supported Baddha Konasana works well whenever the standard hip-opening fold feels like too much stretch to sit in comfortably, and it rewards patience since there is nothing to push against here. Most restorative or wind-down sessions can use it in place of the unsupported pose without losing the seated shape.

Hips too tight for the standard version to feel anything but strained. The blocks remove the stretch sensation entirely, turning a forced position into a comfortable one.
A restorative or longer meditative sit that calls for comfort over stretch intensity. This version is built specifically for staying still without discomfort.
Recovering from an intense hip-opening session and wanting the same shape without more stretch. Support here lets the body simply rest in a familiar position.

For most people with tight hips or a need for a longer, gentler sit, this supported version is the more comfortable choice, and it exists to offer the same seated shape without asking the hips to release into anything.

Getting Ready

A few gentle seated hip circles or figure-four stretches are optional here, since this version is not meant to deepen a stretch the way the standard pose is. Setting the block height before sitting down, testing that the knees will rest without any downward pull, saves needing to adjust mid-hold.

Let the blocks take the full weight of both knees. There should be no sensation of stretch at rest, only support.

Step-by-Step Instructions

1. The setup. Sit down, extend the legs, then draw the knees in and press the soles of the feet together.

2. The blocks. Slide a block under each outer knee, adjusting the height until the knees rest without any pull.

3. The settle. Let the knees fully release onto the blocks, feeling the hips stop working entirely.

4. The sit. Sit with the spine comfortably tall, breathing steadily for the target hold.

5. The exit. Remove the blocks and extend the legs slowly to release.

How Many, How Often

Supported Baddha Konasana is dosed by time held, since there is no active stretch deepening here, only a comfortable, sustained rest.

Level	Where you’re at	What to do
Beginner	New to fully supported seated poses	Hold for 1 to 2 minutes, adjusting the block height until there is zero pulling sensation at the knees.
Intermediate	The support feels settled	Hold for 3 to 5 minutes, letting the breath slow further with each minute.
Advanced	Ready for more active hip work	Move toward Baddha Konasana once a passive, supported seat no longer serves the session’s purpose.

Zero sensation of stretch at rest matters more here than the block height itself, since any pulling feeling means the support still needs adjusting.

Modifications and Variations

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

For more difficulty, Baddha Konasana removes the blocks entirely, letting gravity release the knees toward the floor for an active stretch.

Use this supported version freely whenever comfort matters more than stretch. It stands on its own, not only as a stepping stone toward the unsupported pose.

Common Mistakes to Avoid

Setting the blocks too low, leaving some stretch sensation. This defeats the entire purpose of a fully supported seat. Raising the blocks until the pull disappears completely is the fix.

Rounding the spine now that there is no stretch to focus on. Removing the stretch sensation sometimes lets attention to posture slip along with it. Keeping the spine comfortably tall, even in a passive pose, protects the lower back.

Assuming this version is only a beginner substitute. This version has standalone value for comfort and rest at any experience level. Using it whenever a passive seat is the goal is a completely valid choice.

Holding the breath out of habit even though nothing here demands effort. A supported pose still benefits from a full, easy breath. Letting the breath settle into its own slow rhythm supports the intended rest.

After Your Set

Extending both legs straight out and gently shaking them is optional here, since nothing was actively stretched or loaded. A few slow, easy breaths in a comfortable seated position are enough to transition out of the hold.

Going Deeper

This version is usually trained whenever comfort, not stretch intensity, is the goal, whether that is tight hips, a restorative session or simply a longer meditative sit. The most common way it stalls isn’t hip tightness, but leaving the blocks set too low and unintentionally reintroducing a stretch sensation this pose is built to remove. Adjusting the height until the pull disappears, every time, is what makes this version work as intended.

Someone new to this pose generally finds a comfortable block height within the first session or two, and settles into a full 5-minute hold somewhere in the two to three week range.

How to Know You’re Improving

A 2-minute hold with zero pulling sensation at either knee
A spine that stays comfortably tall without active effort
A comfortable 5-minute hold with the breath settling into a slow, natural rhythm
A clear sense of rest, with no stretch sensation asked of the hips at all

Complete comfort with no stretch sensation, not how low the blocks sit, is what progress looks like here.

Muscles Worked

This pose asks very little of the muscles it involves. The inner thigh (adductors) and hip flexors (iliopsoas) are fully supported by the blocks, not stretched, and only the outer hip (gluteus medius) and lower back (erector spinae) do any work, and only a little, holding the upright seat.

FAQ

If nothing is being stretched, what is the point of this pose? Comfort and rest. Some sessions or some hips call for a familiar seated shape without asking anything to release, and this version provides exactly that.

How do I know the right block height? There should be zero pulling sensation at the knees. Any noticeable pull means the blocks are still set too low for a fully supported seat.

Can I use this version every single session in place of the unsupported pose? Yes, it is a valid long-term choice for anyone who prefers comfort over active stretching, worth keeping around indefinitely.

What can I use instead of yoga blocks? A pair of thick books, a rolled blanket or a firm cushion under each knee all work as reasonable substitutes for the same support.
