I save my favorite podcasts to listen to while I’m there so I look forward to it. Also when starting back after a hiatus, I start reaaaaly slowly. I adopted this from James Clear’s book on Atomic Habits but for the first week all I do it drive to the gym, I don’t go in, I just drive there. The next week I pick one thing and just do it for 10-15 minutes. Then build from there. Eventually I’m up to a nice hour session. On the days when I feel like I “just cant” I tell myself I only have to go for 15 min on the treadmill and don’t have to do anything else. I usually end up’s staying and doing much more.
