Ok so long story short. I'm a skinny guy, I'm like 5'9 and 120 pounds roughly. I doesn't really bother me that much but I think I'd like to put on some muscle. Maybe be like 160 or 170 pounds on muscle instead of the skinny guy I am now. I've always been a skinny person and just don't know enough about gaining the right kind of weight. If anyone here are gym goers or gym veterans could give me some advice because I might be going to one soon. Are there people there that could help me reach my goal? Like what are they called there personal trainers? I don't exactly want people to watch me workout. Ideally I'd like someone to give me a specific meal plan and as well as the right kind of workouts to do for my goal and body type and availability. I also don't eat dairy, junk, or processed foods too much because those flare up my acne. I want to eat clean and healthy so I can't just EAT everything to gain weight. I can only eat specific things to do this. So are there people there that could do this for me? Or give me a plan? A diet that suits my needs and the workouts I should be doing? Will someone there help me with this?
