Lol had not heard this one. The left has "insufficient weightlifting". Might be true.

Could it be that on the left there are more endurance sports, for health. And on the right there are more muscle building sports, so they can strike cool poses with their guns?

It's pretty common. Don't be surprised if you get called a dyel (DYEL, Do You Even Lift) lanklet (small, not fat or muscular) runcell (someone who runs to try to get women, but would be better off lifting).
