It is important for you to stick to the basics until you get to know how your body responds to weight training. People do not respond the same exact way to training and what works for one type will not necessarily work for another. One method of categorizing body types recognizes three different physical types and it is called “somatotypes”.
The ectomorph: short upper body, long arms and legs, long narrow feet and hands, and very little fat storage. This body type has a narrow chest and narrow shoulders and long, thin muscles.
The mesomorph: large chest, long torso, solid muscle structure and very strong.
The endomorph: short musculature, round face, short neck , wide hips, and heavy fat storage.
No one is totally one type but a combination of all three types. Any body type can be developed with the correct training and nutrition however people with different body types will need to approach their training with different objectives, even though they may all have the same goals.
