Consuming the right fats, carbs and protein after exercise will help you recover faster and better.
Whether you do this with “real” food or supplement style nutrition is your choice. Whole food is preferable, but the right supplements are very good.
Whey protein is simply a powder made from milk with a high standard percentage of protein in. It’s often however mixed into supplement mixes with all sorts of other guff in. It can also be cheaper, quicker and more convenient which is why I use it.
Couple of scoops of myprotein unflavoured impact whey, milk/almond milk, banana, berries. In a blender, less than 2 mins start to finish, tasty and nutritious.
It’s useful for me as I consume over 200g of protein a day.
