WLS, Exercise & Calorie Intake?

Hi all! I havent posted in a while. My surgery was Jan 11, 05 & so far, I've lost 40 lbs. Recently I joined a gym and after having my orientation today, the trainer was VERY concerned about my lack of calorie intake. He said I didnt take in enough calories to work out in the gym. Are there any experienced athletes OR WLS folks out there that have any words of wisdom for me? I dont know what to tell this guy. I dont know how to reassure him I am not going to wither away on his gym floor! Thanks for any info you can give me on this subject! Kelly

How about getting a letter from your surgeon oking the exercise? Sara
