2. Use an App

If you know what to do, but you simply don't do it, try using an app to keep track of your eating and exercise habits.

I personally recommend My Fitness Pal;

it's very user-friendly and allows you to follow your friends who also use the app.

With My Fitness Pal, you can keep track of your calories, macros, and other nutrients like vitamins and minerals.

Focus on Building Muscle
