If you are new to fitness, you don't need to eat muscle gain powder or protein powder in the first half of the year. Because at this time, physical progress will be rapid. The effect is also obvious. Because I am a novice and my foundation is weak, it is enough for me to supplement protein with food. After practicing for more than one year, the changes brought by fitness exercise will become smaller and smaller, and the muscle growth will be particularly slow. It is not easy to gain 4kg of muscle every year. Muscle tolerance will not increase because of the previous method. Because the body has gone up, the needs of various nutrients can no longer be met by food supplements. At this time, various supplements are needed, and muscle gain powder or protein powder is one of the best supplements. It can help the body replenish protein quickly and massively, break through the bottleneck and increase muscle latitude.

Therefore, you can't build muscles without eating muscle building powder or protein powder.
