Do I need to do extra exercise to get my abs when i'm skinny?
Hey I’m 18 years old 6 feet tall and 135 pounds. It’s underweight by a few. I don’t each much junk food i try to eat healthy and avoid junk. I sometimes eat something sweet but not much of it. Maybe once or twice a week. I do eat a lot of grapes sometimes I eat a whole package in 1 day. But other than that I don’t eat much sweets and i do plan to cut down. I do this ab workout that really works and i can kind of see and i can feel my six pack coming in. I have been doing some jogging for 20 minutes a day. But since i eat healthy foods and I lift weights for my arms and do an effective ab workout. And that i’m skinny and underweight. Do i need to do some jogging or can I just workout.

You need to eat eat and eat. if you want to build muscle you need to do the opposite of people looking to loose weight. follow this link it will help you establish you energy requirements (http://nutritiondata.self.com/tools/calories-burned) then multiply the result by 1.2 this is the recommended amount for you to build muscle wile minimizing fat gain.
also you need to be eating around 1.8-2.0g of protein per kg of body weight.
All and all to build muscle of any kind you need to eat. I made this mistake for years if you dont eat enough your body canot build or maintain new muscle.
Hope that helps
to tag on to jillian’s post you shosuld eat red meat (beef!!!) or eat some kind of protein to build muscle definitely
