First, thank you to the makers of this site for offering such a great platform. I'm submitting myself to everyone in hopes of seeing better increases in the gym.
My biggest battle is I run 3 businesses. This has me at my desk (at home, thankfully) or in my car almost all of the time. Of the physical activity I get each week, 90% of it comes from my trips to the gym (5 days a week on average).
I'm 6'5" 225lbs and have long arms. I'm trying to fill out and have a look of someone you can tell goes to the gym rather than just looking "fit". So I know I need to eat A LOT to gain that size.
Simultaneously, however, I don't want to have a big gut. My stomach is the only place I gain fat.
Right now my diet is exclusively whole foods- lots of protein (mostly chicken (I use the whole bird) and fish, lean carbs (oatmeal, white rice) and plenty of produce.
Where I am a slow gainer, I try to hit each body part twice per week. My knees are bone-on-bone, so I have to be selective with my cardio.
I would like to hear from the experts on what I can do to get bigger but not wider. Thank you. I have attached a picture of my mediocre body.
