That is a very long day of sitting. When I was younger I had a similar duration commute, with a couple transfers each way. I was fortunate that each line could carry a bike, so I skipped a bus on one end by sacrificing a few minutes to bike a few miles. I would have been in bad shape (mentally, physically, ...) without it. That said, this was one of the unhealthiest periods of my life, and it didn't really get better until I stopped commuting such a distance. The time and effort that commuting saps seems pretty deeply incompatible with an active life. Not a hugely useful observation unless you have the freedom to change it, which many developers do in some way if willing to prioritize it. I know other people who hit the gym at 6am to fit it before the trek into the office, but I've never been one of those. Making exercise a subconscious part of the routine, even if it isn't the most efficient method, has always been the most effective way to get me to actually do it.
