I drew preds wearing exercise clothes so often, I figured I should draw one actually exercising! I also wanted to practice dewlaps, though I don't think I quite nailed it here. Also, I'm pretty sure I've drawn very similar pics to this several times before.
That said, preds exercising is always a fun trope, and I love the idea of a prey getting bounced around in a cramped gut while their pred goes for a jog. Gotta work off those extra calories!
