This is the full quote:

“The researchers note that while they believe these results are causal, more research is needed to prove direct links between specific exercises and mental health. Still, they feel comfortable stating the difference between working out and not working out is the same as ‘between individuals with a difference in household income of more than U.S. $25,000.’”

I am not sure how they arrive at that number especially when they haven’t even proven a direct link.
