It sounds super-gross but please try to imagine it: Red muscles, pink muscles, and white muscles. The red muscles are red because they contain lots of myoglobin: a protein that binds iron and oxygen. Your blood has a similar protein called hemoglobin which binds iron and oxygen.
Red muscle is slow contraction muscle, used in exercise requiring long-time contractions. White muscle is fast contraction muscle, used in fast exercises. Every living person has pink muscle in a certain amount. Pink muscle is a combination of the two other muscles giving you explosive power and stamina. Contrary to scientific belief pink muscle can be built up after extensive workouts with a persons maxed out weight limit.
