I want to quit porn

I have been struggling with pornography for a long time but I really want to cut it down. To put in perspective I jerk off around 3 to 4 times a day and I know it isn't healthy. About 3 times a year i start going to the gym which normally moves my focus but I end up not continuing then falling back. I want to break this habit and find other routes. I should point out that I used to have other hobbies but I think i just need a group to push in the right direction. Does anyone know any good ways to start?
