it improves youre look and teens want to impress girls… thats why

to make them selfs better so the girls look more at them

Self-Confidence
Attracting opposite sex
Health reasons

i guess they do it to be healthy…
and i totally agree with them.

Everyone have different reasons.
They might be doing this to impress girls which is most likely.

I strongly disagree!
The body is still developing. The weight would damage the growth of the bones and would cause health problems in future, mostly you become shorter. You should only start when you stop growing taller around 20.

I’ve got no idea on any research.

So they don’t look too skinny to girls. To improve upper body strength. To work off excess testosterone. To improve overall health. To feel better. To gain self-confidence. To do better in sports. To hang out with other guys (peers). To have fun.

1 - Strength,
2 - Appearance,
3 - Added power, ability/activites for the sports they’re in…

(and all 3 can relate to the opposite sex)

If you have to take time, to explore the OBVIOUS.. then, there’s clearly a future for you in wasting US Taxpayers money, in government… for similar studies.

Teenage boys start weight training because girls like a fit looking guy to go out with.
Muscles mean visible strength and power.
That is a very potent symbol at their age.
They all want to be ‘top dog’.
Getting a 6 pack is more or less essential if you want to get a date.
A 6 pack of strong abs sends a very powerful message to girls.
It says . look at these, I can f*ck all night long.
Whether this is stictly true or false is neither here nor there.It is all about imagery and visual impact.
And let’s be honest about this, a healthy toned and shaped body is an immediate turn on.

Weight lifting feels good.

i’ve always found that when teen age boys take an interest in weight training it is because they are gay and its a good way to be around other boys and men with out anyone guessing it. they can easily check out each others bodies and take showers with other boys and men under the guise of working out .. but its cool. you will meet a lot of guys that way.
