just like cycling hours, not all gym hours are equal.

**some folks** spend a lot of time hanging out int he gym, just like **some cyclists** spend a long time tooling around/getting to the point where they'll do quality work.

juniors can have plenty of responsibilities, but on this forum we've probably got more folks with full-time jobs, mortgages/rent to pay, girlfriends/wives/children/pets, need to do things like prepare meals... all of that limits training time. if mom and dad are paying for the roof over my head, driving me to where i need to be, cooking meals for me, there are more available hours.

of course not true for all people, just a sweeping generality for juniors vs adult athletes.
