2. Muscle lowers your perceived exertion
Adequate strength makes physical tasks and activities (such as rearranging your furniture or simply unloading groceries from your car) easier, lowering what we call your perceived level of exertion goes way down. This can drastically improve your quality of life and help you have energy for other activities or hobbies you enjoy.
3. Muscle enhances immune system function
Muscle is the number one storage spot for glutamine, an amino acid that has an invaluable role in immune function. This means that the more muscle you have, the more glutamate your body can store, and the stronger your immune system will be.
Muscle also makes you more resilient when you do get sick since you have that extra muscle storage and fuel!
4. Muscle upregulates your metabolism
Metabolism drops at 60 years of age (not earlier as previously thought!) Muscle mass can help slow, or even prevent, this decline because it raises your resting metabolic rate, meaning you burn more calories at rest.
More muscle also means you have less adipose tissue, decreased health risks, improved quality of life, and enhanced longevity.
