I am a female in her early 30′s, 5ft. 2, 165lbs (oh no!!!) who just bought a recumbent bike. I needed something non-jarring due to some upper vertebrae degeneration I have. How many minutes per day do I need to be on this bike to see some weight loss results? My diet is the typical American diet, though I am switching to more baked foods and less sodas. Would like to start off with a solid excersise program first, then modify my diet gradually day by day. I have yo-yo’d so many times in the past, with diet pills, starving, and what not, and just want to be healthy this time. Drastic is not for me anymore, as I wish to preserve my health and not be jarring or harmful to my body. Thank you.
