I think you're incorrect.
Not about the Second Law playing a part, I just think that you're misapplying it in this specific case. Either that, or you're turning what should be a symantics argument into one about physics.
Exercise increases the efficiency at which our hearts (and likely other systems, organs, etc...) operate.
So, perhaps it would be better to say that instead of exercise giving you more energy, it allows you to use more of the energy you consume and store, with less waste.
...Although, tbh, I think an argument could be made that it really does give you more. I'm no exercise physiologist, but I tend to think that if you exercise, your body will start burning some of its stored fuel. That, combined with whatever you're consuming on a given day will be burned...
