# The Practice Lab: 30 Evidence-Graded Drills to Learn Any Skill Faster, Break Through Plateaus, and Make It Stick

> A lab manual for adults learning a skill, or coming back to one. Thirty drills, each with an honest badge for the evidence behind it.

The Practice Lab is a 225-page book by Ada Fenwick for adults learning or returning to a skill, like piano, golf, pickleball, drawing or a spoken language. It gives 30 practice drills, each traced to its research and badged by evidence: 5 SOLID, 23 PROMISING and 2 STORY ONLY. Fifteen chapters cover practice, session design, spacing, sleep, plateaus and keeping a skill, with four sample plans.

## A lab manual for the gap between practice and learning

Most practice advice comes as slogans. Put in your 10,000 hours. Practice makes perfect. The research behind those lines is more interesting, and far more useful.

The Practice Lab rests on one sentence from that research: a good practice session often feels worse than a bad one. In a 2001 keypad study, repeating one pattern over and over made practice look better and the next-day test worse. The learners still bet on the repetition.

Each chapter opens with an adult stuck on a skill: a pianist with a spreadsheet of hours, a pickleball player whose drops sail long, a grandmother learning sign language in one long Sunday session. Then it explains what the research found, including the parts that did not hold up. Then it hands you two drills to try at your next session, usually with a pen, a timer and the thing you are practicing.

## Thirty drills, and an honest count

Every drill carries a badge. SOLID means it was tested on people more than once, or a review that pools many studies supports it. PROMISING means real evidence that is thin, small, indirect or mixed. STORY ONLY means a sensible, widely taught practice that has never had a proper test.

The count is 5 SOLID, 23 PROMISING and 2 STORY ONLY. That may look stingy. The book explains why: several famous findings were checked with better methods, and they shrank. A 2022 analysis found no significant effect from cutting back on feedback. A 2024 reanalysis found the benefit of focusing on a movement's effect "small to nil" once publication bias was corrected. A 2015 review concluded that sleep does not enhance motor learning, though it may help you keep what you practiced.

Even the five SOLID drills come with modest effects, and the book says so. Mental practice, for example, showed "a small but significant positive effect" once bias was checked.

## Start where you are stuck

You can read it straight through, or take the fast path through Chapters 2, 7, 9 and 14. If you want to try the approach first, our free guides use the same drills and badges:

If you are also studying for a course or memorizing words, the companion book [Stop Rereading](/books/stop-rereading) covers knowledge: retrieval, spacing and remembering what you read.

## Who it is for, and who it is not

It suits you if you are picking up a skill or coming back to one, like piano, golf, pickleball, drawing or a language you speak. It suits you if you get something right at home and it falls apart when it counts, or if you practice a lot and still feel stuck at the same level. It also suits anyone who wants drills with the evidence behind them, not slogans.

It is not for you if you are studying for an exam or trying to remember facts; Stop Rereading covers that. It is not for practice that hurts. Pain is not part of any drill. See a teacher, coach, doctor or physical therapist. The book is general education about practice methods, not medical, physical therapy or coaching advice.

## What is inside

- The 10,000-hour story, checked: where the number came from, and what the violin study and its 2019 replication found
- The Next-Day Test, a three-minute cold check that shows whether a session actually stuck
- Blocked or mixed practice, and why the big lab advantage of mixing shrinks on real courts and in practice rooms
- Short sessions spread out: the Practice Week Map, one of the best-supported drills in the book
- What sleep really does for a skill, and why the famous overnight boost mostly vanished in better studies
- Practice in your head that helps, and why it adds to real practice instead of replacing it
- Plateaus, breaking a skill into chunks, learning from misses, filming yourself and shaking off the rust
- Four sample four-week plans (an instrument, a sport, a spoken language and drawing) and Practice Log pages

## FAQ

### Who is The Practice Lab for?

Adults picking up a skill, or coming back to one, on top of a full life. The examples include piano at 49, pickleball, golf, swimming, sign language, a guitar chord change and a wedding toast. It is not written for children or for studying facts for an exam.

### Why are so many drills only PROMISING?

Because that is the honest score for this field. Research on learning movement skills has many small studies, and several famous findings shrank when checked with better methods: cutting back on feedback, focusing on the effect of a movement and the overnight sleep boost. PROMISING means real evidence that is thin, small or indirect. The five SOLID drills cover next-day checks, spreading sessions out, practice in your head and watching a good model.

### How is it different from Stop Rereading?

Both are by Ada Fenwick and use the same badges. Stop Rereading is the companion book for knowledge: studying, exams and remembering what you read. The Practice Lab is for skills you do with your hands, voice or body. If you are learning words for a language, Stop Rereading covers that; speaking the language is here.

### Do I have to read it in order?

No. The fast path is four chapters: Chapter 2 for the Next-Day Test, Chapter 7 for the Practice Week Map, Chapter 9 for practicing in your head and Chapter 14 for learning from a model. Those four hold all five SOLID drills. Come back to the rest when you hit a specific problem.

### Is it safe to use if I have an injury?

The book is general education, not medical, physical therapy or coaching advice. Its one safety rule sits above every drill: pain is not part of the method. Stop and ask a professional. If you are resting an injury, ask your doctor or physical therapist before adding any reps, even imagined ones.
