26 & 2 — the hot yoga sequence
A visual guide and memory trainer for the classic Bikram hot yoga sequence:
26 items in order — 24 postures plus 2 breathing exercises — with every
posture's technique, benefits, chakra connections, and muscle-group work.
Features
- Library practice — all 56 additional postures can be practiced individually
or arranged into a saved sequence at
/practice/library. Spoken instructions,
synchronized live figures, adjustable holds, both sides and crossings,
self-paced or automatic steps, and session history. Export/import your
sequences as JSON. Device speech works where a suitable voice is available;
written guidance remains available without speech or WebGL. See
the practice guide.
- Sequence — the full class (about 87 minutes at 60 BPM, plus a
two-minute closing rest) as a visual timeline: opening breath, standing
series, floor series, closing breath, with a class clock.
- Pose pages — setup steps, alignment cues, breath, benefits, cautions,
chakra links with the why, and a body map of what each posture
strengthens and stretches.
- Explore — flip the lens: browse by chakra (root to crown) or by muscle
group (clickable body map) to see which postures work each one.
- Train — memorize the sequence: a spaced-repetition review queue
(SM-2-style intervals) over three card types — "what comes next?",
English↔Sanskrit, and "which posture is #N?" — plus free-practice drills.
Every answer feeds Bayesian knowledge tracing, so mastery is a real
probability, not a tally. The schedule is honest: only spaced retrieval
advances a card (a blitz can't fake a week), misses come back inside
the same session, and the "what comes next" drill chains — each answer
becomes the next question, so a run of right answers is the class
recited in order.
- Knowledge map — the sequence as a DAG: posture identities feed
transitions, transitions feed arcs, arcs feed the whole sequence —
each node tinted by the current estimate that you know it.
- Pace — a metronome-based breath pacer: 60 BPM in six-beat bars by
default (six counts in, six out — the Pranayama pace, five breaths a
minute), adjustable tempo and bar length down to a Kapalbhati pulse,
plus a class pacer that walks all 26 postures on the same clock with
spoken instructions at the right moments — sides, sets, the floor
series' savasana and sit-up interludes — and an immersive full-screen
class mode that keeps the screen awake. The coaching rotates day to
day so the whole of each posture's teaching gets spoken over a week;
Kapalbhati pulses and Pranayama keeps its six-count whatever the dial
says; a quiet two-minute final savasana ends with the bell.
- Rehearsal — turn it on and the class stops telling you what comes
next: the chime sounds, four counts pass, then the voice confirms.
Afterwards, mark the hand-offs you didn't recall; they feed the
knowledge map as class evidence.
- Go deeper — every posture page reads the shape against the classical
repertoire as B.K.S. Iyengar documents it in Light on Yoga: the name's
roots, the nearest classical asana and where 26 & 2 differs, refinements
that transfer, hold-here stages, and the ladder of poses before and
beyond — in our own words, with plate numbers so you can open your copy.
- Moon days — an optional lens, off by default: tonight's moon phase
and the planetary day, a posture of the day (every posture once per
lunar month), and two short notes naming what the day traditionally
leans toward plus one thing to notice. Computed offline; described as
tradition, never as prescription; changes nothing about the class.
A Vedic sky card adds Lahiri sidereal signs, nakshatra and tithi, with sourced Kalapurusha tradition and our own anatomy links.
- Journal — every paced class is remembered: when, how long, what was
rehearsed and recalled; the pacer tells you when you last practiced and
which hand-offs to listen for, and posture pages link straight into a
drill or a class started from that posture.
Installable as an app (PWA) and fully offline once visited — everything
is self-contained. Knowledge estimates decay honestly between sessions:
what you don't practice, the app slowly stops claiming you know.

Editing the sequence
Every posture is one file in src/data/poses/, assembled in class order by
src/data/poses/index.ts — drop, reorder, or swap entries there to match a
studio variant. See CLAUDE.md for the data model and conventions.
