Long Exhale
How to do it
Sit tall in whatever way you can hold for several minutes without effort — cross-legged on a cushion, kneeling, or with your back against a wall and the legs straight out. Breathe in through the nose for a slow count of four, then out through the nose for a count of eight. Keep the air moving steadily on the way out rather than releasing it all at once. If eight is a strain, use four in and six out. Then keep going, and start the count again every time you notice you have stopped counting.
Why it's good for runners
This is the one shape in the method that trains the breath rather than being paced by it, and it is not a soft addition to the practice. A lengthened exhale is the most direct lever anyone has on their own nervous system: breathing out for longer than you breathe in slows the heart on every cycle, and a few minutes of it moves a body out of the switched-on state that a hard training block leaves it in. On a night when sleep will not come, or the day before a race, it is worth more than any shape you could get into.
It also transfers, which the rest of a wind-down does not. An athlete who has practised finding a long, steady exhale on demand can find one at 32 km when the wheels are coming off, and that is a genuinely different last 10 km from the one where the breathing runs away. Controlled breath is one of the capabilities this method is built to produce; this is where it is trained directly rather than as a by-product.
Common mistakes
Don't force the ratio. Air hunger, light-headedness or a gasp at the top of the inhale all mean the count is too long — shorten it, and lengthen it another week. Don't take a huge inhale; the size of the in-breath is not the point and a big one makes the long exhale harder. Don't dump the air out and then sit there waiting for the count to finish, which is a held breath wearing a disguise. And don't treat a wandering mind as a failed practice — it wanders for everyone, within a few breaths, and coming back to the count is the thing being trained.
