Beginning Exercise

I tried my recumbent exercise bike for the first time in over a year. Hopefully it will not cause inflammation in my back. I need to start slowly and with little to no resistance to begin with. I have not lost any weight in over a week and need to do something to get off this plateau. I am hoping this will help. I have had 3 back surgeries so exercise is very limited for me. I have lost 13 lbs but am struggling with the 16 more that I have to go.I am at a standstill right now. But I am determined:happy: in hopes that the weight loss will stave off that 4th surgery I am told I am needing on my spine. Prayers and well wishes are asked for.
