I finally got my gym membership last week. 😆😆😆 So excited. But I never done sports or bodybuilding before. That's why I'm completely clueless right now. For those who were once in similar situation as I am, what routine should I start with? Any secret to share with me?

I am decently thin, but my upper body is fat. I guess that's what people call as "skinny fat". I don't know if I should start with either bulking or cutting. Also, from my first day(and one free session with the gym's personal trainer), I don't have enough strength to complete the full 10 reps of the basic exercises like squats, push ups, sit ups and etcera. How can I get enough strength to do any general exercises?

First of all, I want to say thanks to everybody that took the time replying to my post. All of your advices will not be taken for granted.

Anyway, I still have 2 questions to ask. First question, what kind of routines would you recommend for those who just stepped on to the gym? There are 2 people who were recommended me(OneFarEast, you were not ignored) of their routines and I would likely follow it, but for the sake of curiosity I want to ask more.

Secondly, there are several promoting ads I saw about FitGun on Facebook, and I want to know if it was really effective. Thanks again!
