A comprehensive yoga curriculum includes 50-70 poses, each with a Sanskrit name, English translation, and physical alignment cues. Most students try to absorb all of this by hearing the same names in class week after week and hoping they stick.
This works, but it is slow and unreliable. Cognitive science offers a better method: spaced repetition — a technique that exploits how memory actually works to dramatically accelerate learning and ensure long-term retention.
The Forgetting Curve
In 1885, psychologist Hermann Ebbinghaus ran the first experiments on memory and discovered the forgetting curve: we lose roughly 70% of new information within 24 hours and up to 90% within a week.
This explains a common frustration — you learn a Sanskrit name in Tuesday’s class, recognise it on Thursday, and by next Tuesday it has evaporated. You are not bad at memorising. Your brain is simply discarding information it has not been prompted to keep.
The critical insight: forgetting reverses when you review at the right time. Review too early and you waste effort on material you still know. Review too late and you relearn from scratch. Review at precisely the right moment — just as the memory fades — and the brain strengthens the neural pathway, making it last longer each time.
What Is Spaced Repetition?
Spaced repetition schedules reviews at increasing intervals. Instead of daily cramming, you review material today, then in 2 days, then 5, then 12, then a month. Each successful review extends the interval until the information is essentially permanent.
A comprehensive review in Psychological Science in the Public Interest ranked spaced repetition as one of only two study methods with “high utility” across all ages, subjects, and contexts.
Consider two students learning 50 Sanskrit pose names:
- Student A reviews all 50 names daily for 30 days — 1,500 total reviews.
- Student B uses spaced repetition — roughly 350 total reviews.
After 30 days, Student B remembers more names despite doing less than a quarter of the work.
The SM-2 Algorithm
The most influential spacing algorithm is SM-2 (SuperMemo Algorithm 2), created by Piotr Wozniak in 1987. It powers virtually every modern spaced repetition system, including the flashcard feature in yoga-bits.
How It Works
SM-2 tracks two values per item:
- Ease Factor (EF): Starting at 2.5, this rises when recall is easy and drops when you struggle.
- Inter-Repetition Interval: Days until the next review. Starts at 1 and grows with each success.
After each review you rate your recall. The algorithm adjusts:
- Easy recall — interval multiplies by the EF, pushing the next review weeks or months out.
- Difficult recall — interval resets to a short period, EF decreases slightly, and the item appears more often.
- Failed recall — item re-enters the queue as if new.
A Concrete Example
Learning that Garudasana = Eagle Pose:
| Review | Response | New Interval | Next Review |
|---|---|---|---|
| Day 1 | Correct but slow | 1 day | Day 2 |
| Day 2 | Easy | 6 days | Day 8 |
| Day 8 | Easy | 15 days | Day 23 |
| Day 23 | Struggled | 15 days | Day 38 |
| Day 38 | Instant recall | 38 days | Day 76 |
Five reviews over 2.5 months and the name is permanent knowledge.
Why It Works Especially Well for Yoga
Ideal Flashcard Material
Sanskrit pose names are classic paired associates — each word maps to a specific English name and physical pose. This one-to-one mapping is exactly what spaced repetition handles best.
Finite, Achievable Vocabulary
Unlike learning a full language, yoga vocabulary is bounded: 50-70 pose names plus 20-30 breathing technique names. Spaced repetition conquers this in weeks, not months.
Patterns Compound the Effect
Sanskrit names follow predictable patterns. Once the algorithm locks in “Virabhadra” = warrior, all three Warrior variations become trivially easy. The last 20 poses are learned much faster than the first 20.
Physical Practice Reinforces Memory
Multi-modal encoding — linking information to physical sensations — creates stronger memories. When you review “Utkatasana” and recall the burn in your quads from Chair Pose, you create a rich memory trace that resists forgetting.
How Yoga-Bits Uses Spaced Repetition
The Quiz Game
The 60-second matching challenge presents pose images and asks you to identify the Sanskrit name. Responses feed the SM-2 algorithm — correct answers get scheduled for later; missed poses appear more frequently.
Three Difficulty Levels
All 68 poses are organised into beginner (20 poses like Mountain Pose and Downward Dog), intermediate (25 poses including Crow Pose and Eagle Pose), and advanced (23 poses like Firefly and Scorpion).
The Pose Library
Every pose in the library includes the Sanskrit name, pronunciation guide, instructions, and illustration — an immediate reference when the algorithm surfaces a forgotten pose.
Breathing Techniques Too
The same principles apply to pranayama. With 30+ breathing exercises, the flashcard system helps you learn Sanskrit breathing terminology alongside pose vocabulary.
Tips for Best Results
Be honest with ratings. If you mark an item as “easy” when you struggled, the algorithm schedules it too far out and you will forget it.
Review daily, even just 5 minutes. Consistency beats duration. Five minutes daily outperforms 30 minutes twice a week.
Start with one level. Master the 20 beginner poses before adding intermediate. The algorithm reduces review frequency for mastered items automatically.
Combine with physical practice. Visualise or perform the pose when you see its name. Multi-modal encoding dramatically strengthens retention.
Trust the process. The algorithm deliberately shows material you are about to forget, so reviews often feel hard. That struggle is what strengthens the memory.
Key Takeaways
- Without strategic review, 90% of new information is lost within a week.
- Spaced repetition schedules reviews at the optimal moment, just before a memory fades.
- The SM-2 algorithm calculates personalised intervals based on your performance, so you only study what you are about to forget.
- Sanskrit yoga pose names — finite, pattern-based, physically linked — are ideal material for this approach.
- Yoga-bits implements SM-2 in its quiz and flashcard features across all 68 poses and three difficulty levels.
