Bone structure weight?

[zarxz]

Hi I have been working out for 2 years, 5''8 I went from 116 lbs to 158 lbs and just dieted down to 149 lbs. Even though i added about 33 lbs my weight is pretty small compared to other people at the gym who I look much bigger then, but they weigh a lot more. Their all in the 175-185 range around same bodyfat as me. This comfuses me a lot and my question is really, is it possible that because of my small bone structure make that much of a difference in weight? also could small bone structure explain why my waist size in pants are like 28?

Being less muscular in addition to having low body fat may give you illusion of being "bigger" than someone 40 lbs heavier.

Something's not adding up here. These guys have 30lbs on you, are the same height and bf%, yet you look much bigger?

One of your assertions is not correct.

I forgot to mention their height compared to weight lol
Example: One guy is like 6''1 180 lbs, he has lower amount of muscle mass than me. He is also the same bodyfat as me. still he has 31 lbs more than me. I know hes taller so that could mean some of it but I dont get how he weights that much more. Either my bone structure is incredible small and hes like average
