Friends have told me that I should consume whey protein shake before and after workout. They said this would be effective for building up muscles. However, I have read from a website that I should avoid taking whey protein before workout.
Quoted from the article on the website:
You can have this power drink in the morning, as a snack, in between meals, with meals, before going to sleep, or after a workout, but not before or during a workout.
Is taking whey protein before a workout bad? What is the reason for avoiding to take whey protein before a workout?
