Second major category we're going to look at is the mesomorph, also known as Somatotonic.

们要看的第二个主要类别是胚层，也称 Somatotonic。

For example, I find that I usually can fit into the mesomorph category a little bit easier as I can put on muscle and keep that off fairly easily.

例如，发现通常更容易胚层类别， 因可以很容易地锻炼肌肉并保持肌肉发达。
