The lesson

  1. 1

    Step back and turn the foot in

    One foot steps straight back, then turns in about forty-five degrees. The whole foot lands — heel included. That planted heel is the pose.

  2. 2

    Bend the front knee

    Sink until your front knee is over its ankle, working toward the thigh coming parallel with the floor. Knee tracking over the middle of the foot, not falling inward.

  3. 3

    Square your hips forward

    Your back hip wants to swing open to the side. Draw it forward so both hip points face the front of your mat. This is the hard part and it's where the stretch comes from.

  4. 4

    Arms overhead, ribs down

    Reach both arms up alongside your ears. Let your tailbone drop and your front ribs knit in, so the reach comes from your upper back rather than from arching your low back.

  5. 5

    The test

    You should feel a long pull through the front of your back hip and down into that calf, with the back heel still heavy on the floor. If the heel has lifted or the hip won't square up, shorten the stance until both come back.

How to do it

From standing, step the left foot straight back and turn it in about forty-five degrees, planting the whole foot with the heel down. Bend the right knee until it stacks over the right ankle, working toward the thigh coming parallel with the floor. Draw the left hip forward so both hip points face the front of the mat — the back hip will resist this, and squaring it is most of the work. Let the tailbone drop, knit the front ribs in, and reach both arms overhead alongside the ears. Hold or flow on, then switch sides.

Why it's good for runners

The planted heel is what makes this different from a high lunge, and it's what makes it valuable. With the back foot flat and the hips squared, the stretch runs in one long line from the front of the back hip down through the calf and Achilles — the hip flexor that shortens on every stride and the calf complex that absorbs every landing, lengthened together under bodyweight. Squaring the hips is what gets it there: let the back hip drift open and the line goes slack. It's also the shape that asks most of your ankle, which is the joint that decides whether you roll through a footstrike or fall off the front of it.

Common mistakes

Don't let the back heel lift — that's a high lunge, a good pose in its own right but not this one, and it takes the calf out of the equation. Don't let the back hip swing open toward the side of the mat; that's Warrior II, and it empties the hip flexor stretch. And don't arch the low back to get the arms higher — drop the tailbone first and reach only as far as that allows. If the heel won't stay down or the hips won't square, the stance is too long: step in.
