I used to be very active,gym 3 times a week working as a Psych nurse with non ambulant patients full time which by the way has wrecked my back, and fast walking as many times a week as I could get in. After thumb surgery for osteoarthritis I lost 30% of my grip and it didn't go well on my dominant hand, I still get shooting pain.So all that has made it difficult to go to the gym. I have knee pain now although a knee sleeve does help but the arthritis in my back is the worse so my get up and go has got up and gone. Once I am out of the house I love to walk but my motivation has left me I find I will make excuses to myself to not leave the house. I'm going to be 67yrs old soon and I feel I am just sitting watching TV waiting to die. I should know better and as a retired Psych nurse I should practice what I used to preach about getting out and exercising but I just get get motivated. I think I need a live in trainer.Any advice ?
