I admit that I’m pretty sedentary. I do like walking and swimming however. I like to walk around my neighborhood, weather permitting. In inclement weather there are indoor places to walk, even in a shopping mall! There is a YMCA near me and I have considered joining. I could walk there, swim some laps and reward myself by soaking in the hot tub! My husband discovered an app called Apple Fitness Plus. It is exercises (all kinds, lengths & fitness levels) of videos & music led by trainers that we can follow along with at home. We started with a senior / beginner program. There are various gentle yoga programs. There are programs that can be done while sitting or even lying down (good for wheelchair or bedridden folks). I’m sure you can find something suitable. But for now your upcoming neck surgery & recovery are your top priority. You will be in my thoughts and prayers.
