The purpose of eating protein powder for fitness is to supplement the body with more adequate protein.

Fitness has two purposes:

1, enhance physical fitness.

2. Shape the perfect muscle shape.

These two purposes, no matter which, need the support of nutrients. The most important of these is the need for protein's support. Only when there is enough protein to supply muscles can there be a material basis for growth. ..... Our daily diet contains a certain amount of protein. These protein are enough to meet our daily nutritional needs. However, when doing fitness exercises, it is not enough to rely on protein in food. So you need to supplement yourself with protein by eating protein powder.

This is the purpose of eating protein powder during exercise.

However, it doesn't mean that you must eat protein for fitness. ..... For people who do amateur fitness for the purpose of strengthening their bodies, the nutrition provided by their daily diet is enough, and there is no need to supplement protein, so these people don't need to eat protein powder. ...

I love you.
