It depends on the amount of exercise and your own muscles. If you exercise a lot, you need to eat protein powder to supplement your muscles. Nowadays, milk is pasteurized at high temperature, and many protein have been destroyed. Therefore, when there is a lot of exercise, protein should be supplemented with protein powder.

For those professional bodybuilders, even if they don't exercise or fly, they should eat protein powder, because if protein doesn't take enough, the muscles themselves will decompose. The more muscles you have, the more your body needs protein every day. Daily demand is the demand for protein caused by the body's own consumption without exercise. At the same time, you also need a lot of protein to supplement the process of muscle training. Therefore, if you want to increase your muscles, you should eat protein powder. If the fitness is successful, you should also add some protein powder every day to prevent muscle decomposition.

Eating more meat and egg whites can also supplement protein, but there are many unnecessary cholesterol, fat, carbohydrates and foods that will make you fat and affect the shaping effect after fitness.
