Boat Pose
Navāsana
Balanced on the sitting bones with the legs lifted and the torso leaned back, the body makes a V. Boat is the plainest core-strength pose in the standing-and-balance repertoire: there is nowhere to hide, and the honest hold is much shorter than most people expect.
The shape, with joint angles
The angles are measured on the drawn skeleton and change with the variant you pick. Treat them as a starting reference, not a target to force.

Getting in
- 01
Sit with the knees bent and the feet on the floor in front of you, hands behind the thighs.
- 02
Lean back until the sitting bones are the point of contact and the tailbone is just off the floor.
- 03
Lengthen the spine and lift the chest; the lower back should be long rather than rounded.
- 04
Lift one foot, then the other, until the shins are parallel to the floor — this is the half version.
- 05
Straighten the legs only as far as you can while keeping the spine long and the chest lifted.
- 06
Release the hands from the thighs and extend the arms forward at shoulder height, palms facing each other.
- 07
Hold for 20 seconds, breathing evenly, then lower the feet and rest before repeating.
Working notes
Two poses, and both are real
| Version | Legs | Typical honest hold |
|---|---|---|
| Preparation | Feet on the floor, hands behind the thighs | As long as the breath stays even |
| Half boat | Shins parallel to the floor, hands off | 30 to 60 seconds |
| Full boat | Legs straight, arms forward | 15 to 30 seconds |
| Boat with a strap | Strap around the feet, held in both hands | As long as the strap allows |
The half version with the shins parallel is a genuine pose that many people can hold for a minute after a few weeks. The full version with the legs straight is roughly twice the load, and holding it for twenty seconds with a long spine is a better practice than holding a rounded one for forty.
The rule that decides which version you are doing is not the leg angle, it is the lower back. The moment the lower back rounds, the load has moved off the abdominal muscles and onto the discs, and the pose has stopped doing what it is for.
Why the neck and the arms are never the answer
When the abdominal muscles fatigue, the body looks for help: the chin juts forward, the shoulders round, the arms reach for the knees. All three take load off the core and put it into the neck and the shoulders, which is the opposite of the point.
If you need to hold the thighs to keep going, hold the thighs — that is the preparation version and it is a legitimate answer. Grinding through the full shape with a rounded back and a strained neck is not.
Self-checks
- Is the lower back long, or has it rounded?
- Is the chest still lifted, or has it sunk between the shoulders?
- Is the neck free, or is the chin pushed forward?
- Can you breathe at the same rate you started with?
Safety
Skip or heavily modify the pose if any of these apply to you. When in doubt, ask a teacher who can see you move, or a clinician who knows your history.
- Acute lower back pain or a disc injury: keep the feet on the floor and the torso upright, or skip the pose.
- Pregnancy: skip Boat, particularly after the first trimester.
- Neck injury: keep the head in line with the spine and do not tuck the chin.
- High blood pressure: keep the hands on the floor behind you and the torso less inclined.
- Recent abdominal surgery: get clearance before loading the abdominal wall.
This page is informational only. It is not medical advice and no pose here is a treatment for any condition.
- Half boat with the shins parallel, hands behind the thighs if needed.
- A strap around the feet, held in both hands, lets the arms take some of the load while the spine stays long.
- Legs bent with the feet on the floor and only the torso leaned back, for the first weeks.
- Back to a wall so the shoulder blades can touch it for feedback on the spine.
Useful propsMat · Block · Strap
- A strap around the soles of the feet turns this into a hold most people can sustain with a long spine.
- A block between the knees gives the inner thighs something to do and stops the knees splaying.
- Nothing under the tailbone — a blanket under the sitting bones changes the angle and makes it harder, not easier.
- Acute lower back pain or a disc injury: keep the feet on the floor and the torso upright, or skip the pose.
- Pregnancy: skip Boat, particularly after the first trimester.
- Neck injury: keep the head in line with the spine and do not tuck the chin.
- High blood pressure: keep the hands on the floor behind you and the torso less inclined.
- Recent abdominal surgery: get clearance before loading the abdominal wall.
Steady nasal breathing; if the breath becomes short, the abdominal wall is working past its capacity.
- The breath is the timer here — hold until the breathing stops being calm, then come down.
- Exhale fully at the end before lowering the feet.
- Do not brace the belly and hold the breath; that is a different kind of effort.
