## Summary

When you work out hard, your muscles pump out lactate, the same stuff people used to blame for soreness. Researchers now think lactate acts as a messenger that tags proteins through a process called lactylation, linking your workout to long-term changes in how genes behave. This may explain how exercise protects mitochondria, calms inflammation, and keeps stem cells working across the brain, heart, and muscles. It's still early, and much of the evidence comes from animal and cell studies.

## Practical Takeaway

This review suggests that higher-intensity exercise, which generates more lactate, may drive some of exercise's anti-aging effects.
