7. Yeah the weight gain thing I don't get. Calories in, calories out. Wear a watch that tracks your workouts. Log the shit you eat on an app. Make sure it balances out. It's basically an exact science at this point, I've been doing it for 10 years, I'm 40 years old and I can go up and down the scale at will. Weight loss/gain is only magic till you understand how it works.
