Bone Marrow

There are two types of bone marrow: red and yellow. Yellow contains more fat cells whereas red marrow has a higher blood cell count. When we’re born, we are all made of mostly red marrow. As we get older, more and more of this marrow becomes yellow.

The reason this fact is important is so that you understand how brittle we all become with age. As you get older, have you noticed that it is much easier for you to sustain an injury? Well now you know why. Yellow marrow has a higher tendency for injury. It is crucial that you maintain your bones as healthy as possible through rigorous resistance training: it’s the only way.
