remember, the weight did not appear suddenly. You probably gained it over time. Losing it will also take time. Be patient with yourself. I went from 335lbs to 255lbs 2 1/2 years ago and it was a great experience. It just took some time.

Also, if you have been inactive, your muscles have probably atrophied a bit. Some of your plateau that you are seeing could be muscle growth. You are probably shedding pounds but gaining muscle. Keep spinning and enjoy it. The weight will take care of itself.
