Lol...Girls and muscles. What a unique combination. You made many of us believe that we can never have a girlfriend/wife
I've been skinny my whole life and never had a problem getting girls. If you're trying to bulk up I promise that it won't help, maybe in the short term but at the end of the day its about your mind and heart. If your a good person at the core, it goes a long ways.
you should work hard for it then. go for regular Gym and make a diet chart and follow all the instruction of your trainer. you can easily get this. the results must be shown within 5-6 months.
join and gym and eat a lot of protein. And if she only wants your big muscles, move one friend. There's better gals out there.
