Under modern life the breath drifts fast, shallow and high in the chest. This brings it back in order. Five weeks, one signature practice each, built around a pacer you actually breathe with.
You can't fix the nervous system before the mechanics, or hold a slow resting breath before the body feels safe. Each week sets up the next. Tap a week to load its practice into the pacer above.
Breathing is the one autonomic system you can also run on purpose. Slow it down and lengthen the exhale and you bias the body toward rest: the heart rate settles, heart rate variability rises, and a busy mind gets something steady to follow.
None of it asks for belief. It is mechanics you can feel inside a few minutes.
Pick the week you are on, press play, and breathe with the form. It grows as you breathe in and settles as you breathe out, warming on the in-breath and cooling on the out.
Ten to twenty minutes a day. Morning to set the tone, evening to come down. Nose breathing throughout unless a pattern says otherwise.
