So it's like that polling and pull to is , is thousands of repetitions allowed you to get very good at contracting . But because um I also played soccer and skateboarding , but I didn't do any baseball , basketball or football , muscle groups like deltoids are very challenging to activate and isolate . So I do think that early development is super imposed on a genetic template that sort of predicts which muscle groups are going to be easier or harder to isolate and , and train .
If you can't , you can probably assume about the same thing gonna happen . So , uh , yeah , you'll know , um , this actually the las are actually really interesting , um , because they tend to be one of the more difficult muscle groups to learn how to activate . So , if you're in your journey and you're just like , I have no idea and , um , you can look up like a lap pose .
It's very common to , to have challenges , activating lots . Yeah , I've noticed that many of the muscle groups that were responsible for a large fraction of the work in the various sports that I played as a young child are muscles that are very easy for me to selectively isolate and induce hypertrophy . And um I suppose I'm one of those mutants where my lats happened to be one such of those muscle groups .
And if you do that and you're like , wow , there's no movement here . Just recognize that's extremely common and that it's probably going to take you many , many , many months of trying before you start to see some movements and probably even a few years before you really start to see activation . So you , you're not some sort of like specific , like special genetic anomaly .
It's very , very common . It's uncommon to not be able to activate your biceps , right ? That everyone can do that .
