do people actually exercise after gastric bypass

i here that weight just fall off of them and at first they didnt exercise!!!!

I don't know about other people but I'm exercising now in preparation for my new lifestyle and will get right back to the gym after my surgery as soon as the doctor says it's ok. :)

You are right that weight does fall off at first for most people. BUT, part of the permanent change and long term success that I wanted includes exercise. I started exercise before surgery and continue to this day.

I got on the exercise wagon as soon as I could

Weight does fall off, and some people cannot exercise due to medical issues. However, exercise helps to keep weight off for others. The chance of regain is reduced if one exercises. My surgeon has stressed the importance of exercise from the beginning, and it's much easier to exercise as you're losing, IMO. There was no way I would have been able to participate in a Spinning class 60 lbs. ago. 

Most do.  I did not start until about 6 months out.  I had to return to work 8 days following surgery and that knocked me out!!!

I was very good about exercise for over a year (weight lift and spin classes)...then life happened and gained custody of 2 of my grandkids. 

Working 50+ hours a week an now being a mom again at age 50....I just can't keep up with the exercise.  I have not exercsied consistently in over a year.  I do make sure I take the stairs at work (4th floor...work as a nurse...climb them at least 5x a day) and my life is active.  I have also adjusted down my food intake by about 300 calories a day to compensate for the lack of exercise.

I did! For the first 6 months, I walked daily. For about an hour. Then, when the weight loss slowed, I began working up to harder exercises. Now, I do an hour of hard workout a day, and I'm actually an aerobics instructor! 

i exercise 5x a week and stay very active

My surgeon is the first to say you do not need to exercise to LOSE the weight, but to KEEP it off, you do. Honestly I did nothing until 7 months post-op. My body hurt too much to move. but after losing 100 pounds, I made the commitment to get active. I know it is what has helped me stay under goal at 4 years out. It also helps me mentally. Find a way to be active.

Like you, until I got about 100 pounds off (which only took me down to about 230), I couldn't do anything but walk because I was in so much pain from various parts of my body and got winded SO easily.  I'm still limited by my knee, but I never could have walked up ONE flight of stairs let alone 3 flights as I can now.  I cannot go down the stairs (WAY too much pain), but I am amazed almost every day at work when I go up them (unless it is a really bad knee day)!  I don;t do much, but I do what I can and I know that it DOES help maintain the loss.
