Do you know about iso vs compound movements? I do a lot of iso workouts and I'm pretty big; or as big as I want to be, but I see some skinny fuckers at the gym who are way stronger. I'm not sure if it's age, genetics, or me doing the wrong workouts.

There are different types of muscle fibers in the body, and different people have them in different ratios. This is one reason.
Another reason is a lot of people interested in body building don't stretch off properly after strength training; stretching off allows muscles to grow more densely and prevents muscles from balooning when they repair themselves (but a lot of body builders aspire for a baloon man look).
Finally, improving strength and improving appearance though linked are two different objectives. Often someone working on their muscles for appearance will try to develop relatively small/weak 'vanity' muscle groups for visual impact, such as their pecs or biceps, whereas someone interested in actual strength that is for use and not show will not obsess over making gains in these areas.
I'm sure there are more reasons for leanies having more strength versus big meanies, but these are some of the reasons I recall from when I studied some physiology modules like 14 years ago. I suspect some of my knowledge is now outdated/wrong so I'd love to be corrected / updated!
