Hey guys, just need a few quick tips to finish up my speech for public speaking class.

-Is there an alternate term I can use in place of Body building? There will be females in the audience.

-Besides looking good, what other long term positive effects does working out yield?

-We know protein is the building block used to repair muscles, but what are Essential fatty acids and Complex carbs used for?

-Is there any way I can relate this speech to the females in the audience?

Thanks for your help!
