I am mid fifties, I do Yoga, Pilates and Strength Training at the gym but the amount of outdoor exercise I do has dropped massively since I stopped running due to issues with my knee and hip. I love hiking at the weekends but some days I drive to the office, sit for 8-9 hours then drive home and sit on the sofa, which is not doing me any good.
I live in a tiny rural village so walking from my home in the dark before or after work isn't great (not many pavements or streetlights). For that reason cycling to work isn't a great option in winter either.
I work in an industrial area but there is woodland and a river bank nearby with paths which are popular and I could go out at lunchtime, it would just require footwear and possibly a spare coat at work (I have to dress quite smartly for the job). I have subconsciously convinced myself this is a hassle and I don't have time.
None of this is impossible, I just need to make some new habits I think. Do you make yourself get outside and exercise in winter? Does it make you feel better/help your fitness? Or do you just accept that winter is going to mean more time indoors? I would love to hear from someone who has found that there are real benefits from getting a walk outside every day.
