PA-0284
At a glance
Lying on the back, both legs lower and lift together as one lever. It trains the deep abdominals to hold the pelvis steady against the weight of the legs, and it exposes at once how well the low back is supported.
“Press the low back down and lower only as far as it stays down.”
Essence
The legs are heavy, and the pose is simply a question of how far they can lower before the low back arches off the floor. That point is the working range. Going lower trades abdominal work for lumbar compression, which is why a smaller range with a flat back beats a big range with an arch every time.
Intention
To strengthen the lower abdominals and hip flexors while keeping the low back in contact with the floor.
What this pose develops
Physical
- •Lower abdominal and hip flexor strength
- •Pelvic stability against a load
- •Control of end-range movement
Mental
- •Honesty about working range
- •Steady focus during slow, controlled effort
Teaching concepts
- •Cueing pelvic position before leg movement
- •Offering clear regressions that keep the work meaningful
How to practise
- 1Lie on the back with the legs extended up toward the ceiling and the arms by the sides.
- 2Press the low back gently into the floor by drawing the lower belly in.
- 3On an exhale, lower the legs slowly together, keeping the legs straight.
- 4Stop when the low back begins to lift off the floor.
- 5On an inhale, lift the legs back up to vertical with control.
- 6Repeat for 5 to 10 slow repetitions.
Alignment exploration
Instead of searching for the “correct” position, notice:
- •Low back stays in contact with the floor throughout.
- •Legs stay together and the knees as straight as the hamstrings allow.
- •Neck and jaw relaxed with the head resting on the floor.
- •Hands pressing into the floor or tucked under the pelvis for support.
Breath
Exhale as the legs lower and the abdominals are most challenged. Do not hold the breath. A held breath usually means the range is beyond control.
Teacher’s eye
Stay with the low back. The moment the lumbar curve lifts away from the floor, the exercise has changed from abdominal work to a spinal load. Watch also for the neck, which often strains when the belly is working hard.
Student practice
Reflect after practising:
- •Lower only to the point where your back stays flat.
- •Bend the knees if the straight legs are too much.
- •Place the hands under the tailbone for a little extra support.
Common movement strategies
Rather than mistakes, you may notice:
- •Start with one leg at a time, then both together.
- •Use bent knees to shorten the lever.
- •Progress by lowering the legs a little further each week.
Modifications
- •Knees bent at 90 degrees.
- •Hands under the tailbone.
- •Smaller range with straight legs.
Props
Completion check
- ✓Hug the knees into the chest and rock gently side to side.
- ✓Rest the feet on the floor with the knees bent before getting up.
