Running: I have a friend who runs 30 mins to an hour each day, she loves it but it did take her about 6 months to get really into and now she can not live without. I have tried it but not my thing with bad ankles but many do love it, I do walk about 30 mins to an hour a day sometimes with family or sometimes by myself.
Reading: I go to the library every other week and get a book or two... I like mysteries so I go to that section and find the "girly" colors/covers which usually mean a light read and usually mean easy for me to get into. I have gone through various series already. Sometimes I read a gardening, art history or deeper books but most of the time I like a light read that will just let me get away from the day for an hour or so.
Gardening (flowers & food): Another hobby, I have not gotten into it fully because we are tearing up the yard at the moment for other issues BUT this is something that I enjoy and gets me away from the daily grind. If you are not big into physical outside work this might not be your thing.
Hair cut: Every three - four months I get a hair cut and sometimes I tack on a pedi or manicure. Very relaxing for me and it is a true pamper self type thing but since it is costly only done around 3 times a year.
Message: This I wish I could do more but it is too costly for us. I usually get a message once or twice a year and it is heavenly.
Art: This is another outlet for me, I have an art background so I have set up a small art studio space in the corner of a room. I usually go there a few times a month and paint/draw for a few hours. Nothing much has come from it yet but it is relaxing for me.
Baths: These are the best for me... I grab my latest book, glass of wine or some other drink, light some candles and take a relaxing bath for 30 mins (sometimes an hour). It really restores me to a peaceful calm mind ready to tackle what needs to be done OR gets me in a lovey mood :)
I do want to join some work out class, just have not found the right fit for myself yet or something that fits into my busy schedule.
