The thread i would have commented this in has been closed but i don't believe there is such a thing as an ecto-endo body type. One means skinny frame with long weak muscles and thin boned and the other is stocky and easily stores fat with thick bones. A person with skinny arms a bird chest and a gut is not an ecto-endo they are an ectomorph who is out of shape. A better word for that would be skinnyfat. There is such thing as an ecto-meso and an endo-meso, from what i understand an ecto-meso and endo-meso just have better quality muscle tissue stemming from their genetics. agree? disagree?
