Rehearse in your head: visualization, foreshadowing failure and alter egos
September 29, 2026 · 25 min read
Huberman's visualization protocol, his goal-setting research and Chase Hughes's work with fighters show mental rehearsal can improve real performance, especially when it includes obstacles and failure. It works best as a supplement to practice, not a replacement.
The rules, numbers and steps worth keeping in front of you.
- Mental rehearsal improves real performance, but it supplements practice and never replaces it.
- Huberman: 50 imagined repetitions improved a real finger-tapping skill.
- Keep each visualization to about 15 to 20 seconds, simple and repeated.
- Do 50 to 75 repetitions per session, three to five times a week.
- Rehearse in the first person, and use the same labels as real practice.
- Work on skills you can already do correctly some of the time.
- Imagined plus physical practice works especially well for learning what not to do.
- Use mental training during injury, travel or layoffs.
- Protect sleep; the rewiring happens overnight.
- Huberman: picture the big win only at the start of a goal.
- Huberman: routinely foreshadow failure, then choose the action that avoids it.
- Set moderately hard goals; learning is best at about a 15 percent failure rate.
- Hughes: worrying is rehearsal, so follow a worry with a deliberate good rehearsal.
- Hughes's fighter stories are anecdote, not controlled evidence.
