The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
One of the reasons that it feels like work is because your so called upper motor neurons, the ones that control the lower motor neurons in your spinal cord, which control your muscles, they have to be very metabolically active.

The way that you are able to move the limbs of your body, the way you are able to perform exercise or movement of any kind for that matter, is because as neurons, called motor neurons, send electrical potentials to the muscle fibers, they release a neurotransmitter called acetylcholine, which causes contraction in the muscle fibers, and allows you to move your limbs. Those neurons are also very metabolically demanding, especially when you're doing demanding types of physical work, and that could be cycling or running or weightlifting or yoga or whatever it may be. Those neurons require a ton of glucose.
