I work from home and it's possible for me to accumulate less than 2K steps in a working day.
I've started going for a morning walk which comes in at 5K@55m with the pushchair but it's not something I'm fond of doing in poor weather. The kicker is that even with that I end up around 8-9K steps at the end of the day.
I need to find a way of consistently getting in 60-90 minutes of reasonable exercise, independent of weather that works around having a four and one year old. Gym is not ideal as the nearest one is a 25 minute drive so including changing time you're looking at 2.5 hours out of the day.
