Muscle Mass and Aging
Muscle mass declines with age, especially without resistance training and adequate protein. Preserving lean tissue supports metabolism, bones, and independence.
Muscle mass and aging describes how lean tissue declines from thirties onward—faster with inactivity, low protein, and repeated dieting without lifting. Muscle supports glucose control, bone density, and fall resistance.
Rebuilding requires overload, protein, and patience—not extreme deficits.
Common questions
-
Can older adults build new muscle?
Yes—progressive resistance training and sufficient protein support hypertrophy at many ages. Start with manageable loads and medical clearance if you have joint or cardiac conditions.
