How the 'perfect body' for men went from chubby to skinny to muscular over the last 150 years

Factors like the physical requirements of jobs, availability of food, and cultural trends have influenced our perceptions of humans' physical form. And in the future, journeys into space or the merging of humans with machines might change what we think of as ideal.

Artist Nickolay Lamm has done a significant amount of work on how understandings of an "ideal" female body differ from reality. He wanted to take a look at how Americans' standards for the ideal male body have changed over time as well, so he started collecting photos that depicted that body from the 1870s to today. Then he created models to show how that shape changed over time.

These generalizations don't represent everyone's preferences, of course. And this particular project was focused on body shape and didn't take into account other physical characteristics like skin tone, facial features, or hair color. But these illustrations help show how what we think of as the "ideal male" has changed significantly over the past 150 years.
