Long-distance running makes me feel absolutely horrible, with Tabata 4 minute sprints after 3 minutes I can't feel my legs anymore and I can sleep after drinking 5 cups of strong coffee - does it mean my body is wrong or another scientific article is? I do running because my body needs it but hate it profoundly, and together with long cold showers and weightlifting it's about training my will to overcome unpleasantness to the point of torture. Only once in my life I got runner's high, and it wasn't anything special.
On the other hand, how to change your body to get the leptin response mentioned in the article? If it is genetic, am I out of luck and these kinds of exercise will make me feel horrible all the time?
