Very Mucular at 15

I'm 6'4" and 230lb, and could do with some time on a stairmaster - if I was all muscle at that weight, I'd look like a stallone or schwarzenegger. You have another 35lb on me, and if it really is muscle not fat, that's got to put you in Hulk territory ...

... very impressive for the ladies and turning over tanks, but normal, no, it's out there, off to the right of the scale as far as BMI is concerned.

If it isn't all muscle, then threre are health implications (and even if it is, that's a lot for your heart to sustain) so I'd suggest a visit to a doctor or health clinic to discuss the issue, just as a precaution.

Ok cool yeah my total fat on my body last time i cheked was about 8 - 10 %
i always get told how am i so tall and mucley because my mum is 5,4ft and my dad 6,0ft
and my shoe size 14, is anyone else is this big?
and no i dont do seriods. LOL

8-10% - ok, yeah, I agree you're not fat, just big.

As to anyone else that big? I guess you'd have to go online and do some research in places that like or celebrate muscular fitness - health magazines, male fitness magazines and sites, etc.

If there's no other health question or issue, then I'd say go play: you're big dude, enjoy it, go hurl a tank or something!
