I learnt a great trick about exercise: find a podcast or audio book that you really enjoy listening to. Here's the trick: you're only allowed to listen when you're exercising. Also with food and drink: place friction between the treat and yourself. The easiest example is to not have biscuits / alcohol in the house. Bonus tip: alcohol free beer is really good these days.
If you're exercising for cardio, and you're able to follow your book or podcast, you're probably not doing good cardio. OTOH, it's not a bad way to do interval training while watching sports, go hard when they're yammering, slow down when the sports are happening (or, if you're watching soccer, you can go hard most of the time and then slow down for the replay if anything happens, which is unlikely)
The majority of your cardio should be LISS unless you have extreme time constraints, but most people can find 30-60 minutes per day to get the recommended time in. This is an intensity at which you can hold a conversation.
If you have time for TV, you have time for watching it from a treadmill.
