Individuals over 50 who have never lifted weights can still gain lean mass at a similar percentage of their starting skeletal muscle mass as younger individuals.

“so I want to talk about it whether we're dealing with a 50-year-old woman who comes to you who's never lifted a weight in her life okay so she's the mom of three has never touched a weight um she's going through menopause so now she's actually starting to put on a little bit of weight maybe for the first time in her life so she's actually starting to get a little chubby and you know you wouldn't she's not over weight but she just feels she's you know her clothes are getting a little bit snug and her assumption is I need to do more cardio I need to be more active and it probably needs to be disproportionately cardio and so so you look at her and you make the diagnosis ma'am we can do some cardio we got to put some muscle on you”

“so the the relative increase was similar now they're they're less overall they had less overall Mass they put on because their weight was lower to start and then he said by the end some of them were actually able to add weight like squat extra weight and squat all the way down to a parallel chair which the people in the study were completely mindblown that this was possible for them and it's 16 weeks it's not even a long time you know and we're talking about people who like probably think that they're heading for a wheelchair you know like it is never too late to get active”

“the research shows relative to your starting lean mass regardless of your age or sex you can build the same amount of muscle”
