Can't have it both ways. Can't call something "athletic" when it's the very way, as you described, a scrawny little 10 year old, can do it.
There's a bunch of scrawny 10 year old football, basketball, track & field, baseball, wrestling, jiu-jitsu, volleyball, lacrosse, hockey players (And Bowlers Shocker!) that are much more athletic than most adults.
Where the hell do you think athleticism comes from? From the big Sky-Daddy upstairs? LOL..... It comes from repeating athletic motions that grow fast twitch muscle fibers from a young age. Some call it exercise, some call it practice.
....sorry for the masked vulgarity, I was triggered like a two handed bowler throwing messenger 6 pairs away from me.
And to finish the two handed point that it always comes back to... There's good two handers and there's bad two handers. The people saying "two handed bowling is ruining the sport" or "it's cheating" are solely focused on the success of 5-10
outliers that make up 0.00025 percent of the registered USBC bowlers. Those guys might bowl with 1% of this website in 1-2 tournaments a year and there's even a greater chance that you'll cross with them, much less be affected by their lane play.
If you're worried about a future of 8 two handers to a pair on a league night with 5-man teams then, I understand. But by then, it'll be time to join the Monday Morning Holy Rollers Senior leagues.
Have fun kids! (*Unless bowling)
Follow your dreams kids! (*Unless it's to bowl like Belmo)
You can be anything you want in life if you work hard kids! (*unless you wanna be a lousy cheating 2 handed bowler)
