it seems from this that it depends on when people become the most focused and serious about it, which can be any age. i was curious about an answer to this too, but im not sure. im only 21 but i think im fairly close to being at my strongest. theres not really anything else i can change to make much progress, my workouts are way more intense than anyone i know and my diet and training is pretty clean. kinda depressing then that im not gonna gain a whole lot more. i gained a lot fo strenght recently and im maxing out many of the weights in my gyms. oh well, il see. so in response to this it doesnt really seem to be any inherent age issue, just depends on when people become the most dedicated? i could be wrong lol
