How can I improve my working memory?

The short answer

Working memory can be improved — but it requires the right approach. Not all "brain training" actually transfers to real-world gains. Here are the methods with the strongest scientific evidence:

The data

Method	Expected gain	Difficulty	Evidence
Chunking (grouping digits into patterns)	2–3 digits	Low	Strong
N-back training (dual n-back protocol)	1–2 digits	High	Moderate
Aerobic exercise (150 min/week)	1–2 digits	Moderate	Strong
Spaced rehearsal	1 digit	Low	Strong
Quality sleep (7–9 hours)	Prevents loss	Low	Very strong
Stress reduction (meditation, NSDR)	0.5–1 digit	Low	Moderate

What it means for you

The fastest way to verify improvement is regular testing. The Number Memory test gives you a consistent measure of your phonological loop capacity. Test once a week under identical conditions (same time of day, same sleep, same hydration) to track meaningful change. Also try the Sequence Memory test which loads the visuospatial component of working memory.

Quick Answer

Chunking, spaced rehearsal, N-back training, aerobic exercise, and quality sleep are the most evidence-backed methods. Gains of 2–3 digits are achievable.
