I see a lot of sarcastic comments, but even Kurzgesagt released a video that talks about how exercising doesn't really increase energy expenditure. The theory/findings were that we tend to have a consistent allocation of where energy is spent. Maybe if you start exercising tomorrow, you'd be expending more energy than before, but there was research suggesting that over a month, you'd be expending the same amount of energy as you usually did, by reallocating where the energy is spent.

This research just reinforces that exercising doesn't affect reallocation of energy expenditure.

But that being said, this seems like it was a 2-week experiment, and doesn't disprove that maybe across months the body gets used to the exercise, and reallocation happens.
