Trigger-action planning. (Official literature calls it "Implementation Intentions", but that's a terrible name). The gist of it is to tie a particular sensory experience to a particular action you want to take. Putting a pull-up bar on your bedroom door is a great example - then, every time you go through the door, you can exercise with the pull-up bar. For reddit, you can either trigger off of "opening a reddit tab" or scrolling to the bottom of the current page, and close the tab when that happens. Another approach is to figure out what you get out of browsing reddit, and finding better ways of getting the same stuff. Odds are it's a combination of a low-risk activity, encountering novel information, and a strategy for not doing things that you "should" do but don't want to. If you're reliably getting safe and interesting information from a reading list and procrastinating through exercise, then you may well find that you've solved the urge to visit reddit.
