Why muscle matters
Muscle supports movement and strength. Changes vary between individuals and cannot be guaranteed by one habit.
Resistance training
Progressive strength work may help maintain or build muscle when appropriate, but it should be adapted to the person.
Nutrition and recovery
Regular nourishment, adequate protein and sleep can support training and wellbeing.
