The Four Body Types
The Body Types you see in the above image are Generalized. A Body Type Two (BT2) can look Nearly Identical to a Body Type One (BT1), a Body Type Three (BT3) like a BT2, Body Type Four (BT4) like a BT3, and such -- especially the younger one is.

Summary
A Body Type One (BT1) Body, starting from birth, is most in balance relative to all other The Four Body Type body types. A Body Type One has a high probability of being more symmetrical. A Body Type One usually requires much less maintenance in terms of Diet, Exercise, and Lifestyle to avoid obesity, especially earlier in life. A Body Type One is usually fully ripped and symmetrical, or easy to attain with little effort.
A Body Type Two (BT2) Body, well taken care of, can look almost identical to a Body Type One. However, a Body Type Two has a tendency to be less symmetrical. A Body Type Two usually requires more maintenance than a Body Type One in terms of Diet, Exercise, and Lifestyle to avoid obesity. With more effort and diligence, Body Type Two can be fully ripped and symmetrical. However, building muscle using machines or other such repetition without true consideration of true body structure, can be a real waste of time and energy in the long run.
A Body Type Three (BT3) Body is usually much less symmetrical and requires much greater effort in terms of Diet, Exercise and Lifestyle to manage obesity. Avoiding obesity entirely can be very difficult, and becoming at least somewhat skinny fat is a strong probability. A Body Type Three, especially as it ages, is usually much less symmetrical and has a much harder time achieving ripped status of any degree. Fully ripped status is not really possible.
A Body Type Four (BT4) Body is the least balanced of all Body Types, is usually not symmetrical, and requires monumental effort in terms of Diet, Exercise and Lifestyle to manage obesity. Avoiding obesity entirely can be almost impossible, with the end result of avoiding obesity being skinny fat, which, can be as difficult to live with as being morbidly obese. A Body Type Four, especially as it ages, is usually very much less symmetrical, if symmetrical at all, other than round. Achieving ripped status is very difficult most any way, and fully ripped status is impossible without honest knowledgable intervention and Herculean effort.
