Depends on many factors, but yeah. If he’s got a more protein based diet than you do, if he does more physical labour than you do, if he works out more than you, etc.
Maybe his diet and exercise, he's still a teenager.
Hormones can play a role too. Higher testosterone levels build more muscle easily. He could be higher in testosterone than you since he’s more hormonal as a teenager going through puberty.
He's definitely gotten more hormonal, he couldn't over power me a year ago, he did this time.
Also already has a girlfriend.
Age doesn’t have much to do with muscle mass. Eat a diet high in protein and work out
