My friend is overweight... ok he's obese, so I would classify him as an endomorph. An endomporph is one who gains weight easily and supposedly gains muscle fairly quick as well. This is where the whole division of body types gets a little fuzzy for me. This friend and I had a good 4 month period of lifting together, so I got a first hand view of his strength gains during this time period. He started at the same weight I did for exercises and after 4 months we we're still even as far as strength is concerned. So after this long post I ask if there are endomorphs who gain weight quickly, but muscle slowly? Are there ectomorphs who gain weight slowly, but strength quickly? I have heard of body types blending, but not too knowledgable on this subject. Is my friend a blender? or is there another good explanation for this? Thanks for your patience and any info you may provide!
