Hey guys. What would y'all recommend for someone just starting a workout? I am 13 years old 5'3" and 110 LBS. Plus I don't gain weight easily at all. I have a nice advantage because my parents have a package to subscribe us to a local gym but I haven't used it but I plan on using it if I can get a good plan setup. So can y'all help me out? I am currently trying to develop a 6-Pack. If y'all need any more info I'd be happy to help.
