Can the landlord tell me your weight and height? Let me see if you are thin or fat! Let me answer your question first: Protein powder is divided into plant protein and whey protein. Plant protein is mainly soybean protein, which is not necessary for fitness enthusiasts. We mainly eat whey protein. Whey protein can repair damaged muscle cells and fibers and make them stronger. The premise of eating protein powder depends on your training. Generally, start eating about 30 minutes after exercise, and a spoonful is enough. You can eat a spoonful in the morning, not too much. The spoon is from the protein powder bucket!
