Health math is counterintuitive.
Example (extreme): Suppose you work 12 hours, 6 days per week because that's all you have available.
12 * 6 = 72 hours per week.
Now suppose you decide to add exercise, 1 hour per day, 6 days per week.
You'd intuitively think that would leave you with 6 less hours for work,
72 - 6 = 66.
But the exercise could improve your health (and therefore your effectively while at work, let's say by 10%)
Then you'd have 66 * 1.1 or 72.6 hours of effective work.
So by exercising an hour per day, you get more work done.
I realize the assumptions and the math are oversimplified, but you get the idea.
No reason for a tradeoff when none is needed.
