Ethan_1990 saidHey guys! I need all advice as to how I can build up my pecs. What kind of exercises work well for building muscle in my pecs? About how long before I will start to see prominent results? Should I go for 8-10 reps, 12-18 or mix it up? Any and all tips are greatly appreciated!
You are way to thin for your height. I'd suggest to focus on getting stronger.
Start a "power to the people" like program with only deadlifts and incline bench press. Your pecs will come along with the rest of the body.
Don't water down your energy with isolation exercises at this point( at least not for a few years).
However, you must make sure you get 8 hours sleep and eat a little bit more than your maintenance level.
