Explosive F13 Eat lots of protein when you are trying to gain muscle. Protein is the basic building block for muscle cells. If you're not getting enough protein in your diet, you can lose muscle mass instead of gaining it. Depending on your body weight, each day you may require 1 gram of protein.One of the most important things you can do to aid in muscle building is to stretch after working out. An individual who is less than 40 years old should hold their stretch for 30 seconds or more. Someone over 40 should hold their stretches for at least 60 seconds. This can ensure your safety while building muscle.
