DAILY YOGA ยท Parsva Bakasana
Side Crow
Parsva Bakasana โ Side Crow โ is a twisting arm balance where both knees rest on one upper arm while the body floats sideways. It combines a deep twist with the arm-balance skills of Crow, building core power, wrist strength and fearless focus.
Name meaning: From pฤrลva meaning "side", baka meaning "crane" (or kฤka, "crow"), and ฤsana โ the "side crane/crow posture", a twisted arm balance. Strictly Crane has straight arms, Crow bent.
Classification: Asana โ a twisted arm-balance (a lateral variation of Crow/Crane).
Tradition & origin: The Crow/Crane family is genuinely old โ Bakasana is listed in the 17th-century Hatha Ratnavali and drawn in the 19th-century Sritattvanidhi. This asymmetric Side Crow variation, however, is a modern development of that family. So the base is old; this twist is modern.

How to do it โ step by step
- 1Squat with the feet together and twist the torso to one side.
- 2Plant both palms shoulder-width on the floor, level with the twist.
- 3Bring the outer edge of the top thigh onto the upper arm (near the elbow shelf).
- 4Bend the elbows straight back to create a shelf, hugging them in.
- 5Shift the weight forward until it moves off the feet into the hands.
- 6Gaze forward and lift both feet, keeping the knees stacked.
- 7Lower with control; switch sides.
Breath & hold
Breathe steadily; hold 10โ20 seconds each side. Do not hold the breath.
Benefits
- โStrengthens the arms, wrists, shoulders and core.
- โDeepens spinal rotation.
- โBuilds focus, balance and confidence.
- โPrepares the body for deeper arm balances.
๐ช The traditional / desi way
- The "side crow" โ the same poised bird as Bakasana, now perched at an angle, adding a twist to the balance.
- Traditional cue: look forward, not down; the fear of tipping forward eases the moment you commit to the gaze and the shelf.
Common mistakes
- โLooking down (which tips you forward).
- โNot creating a firm elbow shelf for the thighs to rest on.
- โFailing to shift the weight fully into the hands.
Modifications & props
- ๐งฉPlace a cushion in front for confidence.
- ๐งฉKeep the toes lightly on the floor while you find the twist and shelf.
- ๐งฉPractise the twist in a squat first (Parivrtta Malasana).
Muscles & anatomy
- ๐ชWorks the wrists, arms, shoulders and deep core, plus the obliques in the twist.
- ๐ชThe twist compresses and engages the waist to create the balancing "shelf".
- ๐ชA firm forward gaze and rounded upper back keep the balance.
What you may feel
- ๐ซงNormal: strong effort in the arms and core with a firm twist through the waist.
- ๐ซงWarning sign: wrist pain or tipping forward โ cushion the floor ahead, gaze forward, and build strength first.
Variations to grow into
Keep the toes lightly on a block or the floor while you find the twist and the elbow shelf.
Extend into Eight-Angle Pose (Astavakrasana) or a one-legged variation for a greater challenge.
Using props
- ๐งฑA cushion in front to remove the fear of tipping.
- ๐งฑA block under the feet to find the lift.
Warm-up & counterpose
- Wrist mobility, CatโCow, and revolved-squat twists to warm the wrists and spine.
- A gentle wrist counter-stretch and a forward fold or Child's Pose.
Supporting exercises
Why: Builds the arm-balance base before adding the twist.
How: Balance the knees on the upper arms with a forward gaze.
Why: Grooves the twist used to set the shelf.
How: In a squat, hook one elbow outside the opposite knee and twist.
Progression path
Master Crow, then practise the twist in a squat; set both thighs on one upper arm, keep the toes light, and shift the weight forward until the feet lift.
Who it suits โ and who should modify
- โPractitioners comfortable with Crow (Bakasana) wanting to add a twist.
- โThose with reasonable wrist, shoulder and core strength.
- โPeople building toward deeper twisted arm balances (Eight-Angle, Koundinyasana).
- !Wrist injury or carpal tunnel โ build wrist strength first or skip.
- !Pregnancy โ avoid the deep twist and compression.
- !Recent abdominal or wrist surgery โ avoid.
When to practise
In the stronger, warmed part of a practice, after wrist and core preparation.
A couple of times a week; build the hold gradually.
Traditional view vs. modern evidence
The poised crane/crow, turned to the side; a balanced, focused bird.
The Crow/Crane base is old (Hatha Ratnavali, Sritattvanidhi); this side variation is modern.
Valued as an accessible twisted arm balance and a step toward Eight-Angle.

Evidence at a glance
Side Crow builds wrist, arm, shoulder and core strength and balance.
Consistent with the biomechanics of a twisted hand-balance.
It detoxifies the abdominal organs.
A traditional-style claim offered without supporting evidence.
Myths vs. reality
โ Myth: You need big arm strength for Side Crow.
โ Reality: It is mostly a firm twist, a solid elbow shelf and a forward weight-shift โ leverage and gaze matter more than raw strength.
โ Myth: Twisting arm balances detoxify the organs.
โ Reality: They build strength and feel invigorating, but the squeeze-and-detox idea is a metaphor, not an established mechanism.
โ ๏ธ Cautions
- Wrist injury or carpal tunnel โ build strength first and practise cautiously. Pregnancy โ avoid (deep twist + compression).
