The topic that occupies the minds of so many youth , young men , but also a lot of women . I think one of the really interesting progressions that's taken place in the last decade or so , is that far more men and women are using resistance training in order to evoke hypertrophy growth of muscles for aesthetic reasons and for all sorts of reasons , what are the ways that people can induce hypertrophy ? So not to correct you or insult you , but probably a better way to think about that question is really what stimuli do I need to give the muscle to induce hypertrophy .

What's driving changes in hypertrophy is much more well rounded and so you have options to get that . Remember , you're training a movement and now you're training a response and a muscle that causes the growth that's very , very different . So if we look at like the classic dogma , we have to basically challenge the muscle to need to come back in this case , specifically bigger and the nutrients need to be there to support that growth .

So I can get there with a lot of frequency and a moderate signal I can get there with very low frequency and a large signal like more akin to what you did with , with Mike back in the day , I'm sure and still train that way , still train each muscle group mainly once a week directly and once a week indirectly . So all you can , all you have to do there to not fail is to make sure the training is hard enough . And it's gonna work .

OK . Other ways say a higher load , maybe uh as heavy as you can for say , eight repetitions is gonna get through through what's called mechanical tension . Uh And so there's there's these different paths so we can get to the same spot .

As long as one of those three variables is high , you're gonna get there because the mechanisms that are needed to activate that signaling cascade are wide ranging . And this is why when we even see things like blood flow restriction training , right ? This is when you put like a cuff on your arm or your leg and you block blood flow and you use no load or as low as say 30% of your maximum .
