Honest limits
What this study does not prove.
This is a narrative review, not a new intervention trial. Human evidence for exactly how cellular memory changes retraining speed is still incomplete.
Kris's practical takeaway
Here's what to do with it.
Training history can help explain why returning lifters often regain capacity, while the practical comeback still depends on lifting, food, sleep, and patience.
What to remember
Three useful reminders.
Your body remembers, but it still needs a real comeback plan
Past training is an advantage, not permission to rush
Muscle memory includes open questions
