Is this really surprising?
Physical fitness, IQ and income are all positively correlated.
Real life isn't an RPG where you only have so many stat points to assign, being healthy or living well are going to improve all of the above.

Well, but there are only so many hours in a day. If you're lucky, then you don't have to work so hard on one or more of the aspects you mentioned (smarts, looks, income, etc.), but if you're not then you may have to put in effort in all three or more.
Maybe that's not true for al (although a 35 minute bike ride with existing fitness gets you a long way surprisingly fast). But one can lift while watching TV. One can do squats while doing laundry. Etc.
Of course, in each case, one of those two options is far less comfortable. For commuting that's particularly true in the winter. But WRT physical fitness, the barrier is almost always "discomfort" and almost never "time".
