I need help asap! Im am 30 years old and I am very overweight. Ever since I got an epidural 10 years ago during labor I have had a horrible back. I can't even stand or walk longer than 5-10 mins. When I had my baby I was 149 now 10 years later I am 420lbs. I can't lose weight bc I cant walk long or run and a couple years ago I found out I have osteoarthritis in my knee so that makes it worse. I tried diet pills and eating better but nothing is working. I have a sedentary life because of my back and legs. Im scared im going to die early and I want to live long for my kids and husband. Does anyone know any exercises that I can do that won't kill my back or knee or any tips to lose weight. Im desperate!!!!!😭
