Individuals should maximize muscle mass gain before age 50 because muscle is difficult to retain later in life.

“Muscle atrophy begins at ~50.”

“finally it's very important when people are still able to put on muscle that they put on as much as possible because once you're in the over 50 category you're kind of clawing on for dear life and trying to keep as much of that muscle as possible”

“it's very important when people are still able to put on muscle that they put on as much as possible because once you're in the over 50 category you're kind of clawing on for dear life and trying to keep as much of that muscle as possible so I don't really want people entering middle age with a muscle deficit”

“Establishing a solid foundation of muscle mass before the age of 50 is crucial.”

“This means by the time we're in our 70s and 80s, we're left with just 60-80% of the muscle mass from our 30s.”

“Peak muscle mass happens around between the ages of 20 and 30 and then after that you know so as you start to get in your 40s and 50s you lose about 8% of muscle mass per decade once you get into your 70s 15% of muscle mass per decade”

“yet when the average American reaches age 50 they lose about 10% of their Peak muscle mass by the time they reach age 70 they're losing about 40% of their Peak muscle mass”
