There's more to exercise than just mitochondrial adaptation... Presumably by inhibiting that, yet still demanding some adaptation from your body (by taxing it with strenuous exercise), you're promoting other adaptations? It might be beneficial somehow. Also, AFAIK more active mitochondria might not be a good thing (more reactive oxygen species damaging your cells, more chances of mitochondria mutating maybe causing cancer). Anyways, I'm not a professional, just a hobbyist follower of anti-aging community. For what it's worth, Peter Attia, an anti-aging doctor whom I follow, recently said he stopped taking metformin after having taken it for years.
