Just a forum to talk about the above. Maybe you're ex-military, maybe you've joined the railway after working for the emergency services? Maybe fitness and wellbeing is your passion..... How do you maintain your routine whilst working railway shifts? How do you manage that work/life balance snd still squeeze in time for the gym? What do your workouts involve? Go on....be the first one to post, lead by example! 
To be honest, it’s potentially a major problem. However my plan is as follows:
* Target of 1000 calories worth of exercise per day (as measured by Apple Watch) which I generally do without exception.
* 2 runs per week, normally around 9 miles but the occasional half or full marathon every month or two. Runs normally HR zone 2 but with a sprint finish for the last mile or two. Every fourth or fifth run replaced with a HIIT run.
* 1 to 2 swims per week except during school holiday times, normally a straight mile but sometimes replaced or supplemented by other variations subject to how I feel on the day
* Gym 1-2 times per week
* Rowing machine at home 1-2 times per week, during summer months very occasionally real rowing.
* If the above doesn’t achieve the target for whatever reason then will walk, stair climb or do calisthenics, often during work time where feasible.
* When on holiday away from home much of the above will be replaced by a significant amount of walking, though with the occasional evening run where feasible. When on holiday generally have no problem doing 1000 calories a day without special effort as tend to be highly active.
One big risk is overtraining, in other words fatigue resulting in not getting the best value out of exercise. With the caveat again that watch measurements aren’t necessarily that accurate, I’ve noticed a conspicuous drop in measured VO2-max coinciding with long weekend shifts or 7 days in a row at work, which can take some time to recover.
