I did the same while at my old job, since it was literally across the street from a gym. I went to the gym during lunch every day, where "going to the gym" just meant turning up and getting changed.
Going during my lunch hour worked better than trying to go in the morning or evening, since I was already constrained to be nearby at the start and end of that hour (plus I don't drive), whereas outside work it was easier to sabotage myself by thinking that I could be doing something "more productive".
There are always plenty of excuses in the moment too, so I adopted a mindset where going to the gym was a given, and anything that encroached on that was an inconvenience; e.g. if I had some errand to run I would instinctively plan to do it before or after work rather than at lunch. As someone who tries to be helpful and humble, it really took effort to prioritise my own wellbeing sometimes!
Another trick I did was to mark every (week)day that I turned up at the gym with a big X on a physical calendar, which gamified it by trying to avoid breaking the current "streak".
Probably worth saying that it worked too! I focused on strengthening my arms (e.g. if I was only there 10 minutes then that's all I'd do) and they went from mostly fat to noticably muscular after about 3 months.
Unfortunately I moved a few years ago and never managed to get back into a good routine :(
