warming up (waffffeeeeeeenn)

I'd been walking for hours and, as usual, I'd lost track of where I was, when I suddenly realized I'd reached the city limits. I immediately felt happy and, without hesitation, passed beyond the barrier and found myself walking between cultivated fields and meadows. I didn't feel tired at all. On the contrary, every joint in me was as relaxed as if a load had been lifted from my shoulders.
