Right now I am pretty thin, about 135lb, but I'm 6 feet and I really want to put on some muscle fast.
There is a gym close to my house and I was going to sign up there, but it seems that I won't have any time. I basically have 3 hours free weekday after I come back from work and before I have to go to sleep. So I guess I can give 0.5-1 hour each day if necessary to work out or do whatever. Right now I am just doing bicep curls and push-ups, I have 20lb free weights and Its hard for me to even do more than 15 in one rep, so I am pretty weak I guess. I also am trying to take some protein shakes, but the thing is that I have been doing something like this for a while, and haven't seen any real good results. I was reading another similar blog post, and there were lots of ppl saying that you should focus on "core" exercises. I'm not sure exactly what this means (other than working out your core) because I want to get bigger arm/chest muscles mainly.
So, I was wondering if anybody can recommend exercises which I can do without weights, or with my small freeweights which I have right now.
With regards to my diet, after reading a bit I figure I'll go and get some tuna and eat a lot of that, as well as cottage cheese, and maybe continue to take the protein shakes. How often should I be taking protein shakes?
