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)
However I can definitely listen to a podcast when using a static bike... As long as your heart rate is 75‰
