I'd like to add some important points here:
1. The finances are a problem for many poor people. But it can't be an excuse not to do bodybuilding at home or in the parks, gardens, fields, etc. There are many other ways to build muscles (free ways) like push-up (
https://en.wikipedia.org/wiki/Push-up) and pull-up (
https://en.wikipedia.org/wiki/Pull-up_(exercise)) for example. You don't need a gym if you really want to get fit.
2. "a short stature, small physical frame, or less than attractive face" -- all of these with a combination of a muscular body are a better combination than those obese and/or unattractive males (like 2/10 to 4/10) who still get girlfriends out there by some reason/reasons.
3. It's not necessary to become a "Chad" ("Chang", "Chadpreet", "Tyrone", etc.) in order to ascend. I often see these this type of males (around 7/10 to 9/10) with average females (around 2/10 to 6/10) and at the same time many average or obese and unattractive males with prettier females (like 7/10, 8/10, 9/10...) This makes me think that the body and face are not that important how many incels think and that there are sometimes more important factors like location, good luck (like the right timing), money, characters, habits and so on. So to have a better body and a better face is useful, but not universal means.
4. And "this difference was significant in males" is okay for the male unattractive incels because it shows exactly that there is more chance for them if they develop themselves in other fields (body, money, status, knowledge, education, better locations and so on).
