Sitting around on the cardio machines in the gym makes me want to kill myself too.
Just do something that is enjoyable. Some ideas:
hiking
swimming
rope flow
riding an actual bike
rowing an actual boat
martial arts
squash
VR sports games

According to my watch I burned more than 800 kcal yesterday by walking to the local park, juggling clubs and balls for an hour, and walking back home.

I keep it simple by always eating my BMR and then creating as much of a deficit as I want through exercise.
