To be fair he's probably a young lad just starting out. I remember when I was about 14 or 15 and just started working out I thought if I did lots of running I'd get nice big muscular arms and legs

I used to think to guys like Arnie and Stallone would be able to beat virtually anyone in a race because their huge muscles would power every stride.

When your a kid, unless you learn from somebody or something you don't automatically just know which exercises and sports are good for what.

Cut the kid some slack
