Yes, a man in his 80s can still have good muscle mass

Yes, a man in his 80s can still have good muscle mass, and in fact, research shows that it's never too late to start building muscle:
Muscle loss is normal

• As people age, it's normal to lose muscle mass, strength, and function, a condition called sarcopenia. This process can start as early as a person's 30s.
  Strength training can help
• Strength training can help people maintain and rebuild muscle at any age, and older adults may see even greater improvements than younger adults.
  Research shows it's possible
• Clinical trials have shown that adults over 75 can significantly increase their muscle mass and strength through progressive resistance training.
  • Exercise machines can help
    Exercise machines like elliptical machines, recumbent exercise bikes, rowing machines, and lat pulldown machines can help build muscle mass.
    Tips for staying strong
  • Some tips for staying strong include moving mindfully, setting realistic goals, and making strength training part of your daily routine.

I certainly hope so. I am 65 and it is becoming more difficult to gain muscle mass. Hopefully I can keep some of it as I grow older.
