Weight Training = 2 lb weight gain?

 Hello all!
So far since 2 weeks pre-op diet for surgery, I have been consistently losing. I have not had a single stall or gain (I know, I'm very lucky), but I say this as a "up till now" kind of situation. I am almost 9 weeks out, and so far, most everyday I have been doing a walk or lighter exercise. Nothing too serious. But seeing as I want to be healthy AND thin, I decided to start serious cardio and weight training yesterday. Boy, I began to get sore a few hours after I worked out! But then, this morning, I got up to a 2 pound gain on the scales?!? (And I know it wasn't anything I ate).
So I want to know, is weight training an exercise that should be started at this point in my journey, or should I wait until later on when I've lost more weight? While I say that I want to be healthy (I do) but I, as many others do, have a certain number in mind that I want to achieve. So will weight training help me to get to that number or halt my progress? Should I just stick to walks?
Thanks for any help, I'm a little baffled.

Totally normal! Keep on keeping on. Make sure you are getting enough water and you will see the scale move again.

Weight training takes a while to make a difference.  Perhaps this was normal fluctuation in the scale.  As you build up strength, it is important to focus on inches and endurance, and not the scale.  Good toned muscles can weigh more than fat.

When you do weight training, you are stressing your muscles, causing little tears in them which then repair and build muscle. Maybe that's a little simple, but it's something like that. Anyway, as they repair, they absorb water and thus the gain, especially in the beginning. So it's totally normal that you gain weight at first, but the long term benefits far away the water weight.

Thanks for posting this ......I am just trying to figure out what I am doing wrong

I work with a personal trainer 3 days a week to try and get to my goal of being completely healthy and in great shape. For a period of almost 3 months my weight number remained constant but I lost 2 pants sizes. That coinsided fairly well with our adding weight training to the mostly cardio routines we were doing.

I will say that weight training has helped that flabby, floppy skin feeling that I really hated. I've had people comment that you wouldn't know I'd lost almost 200 lbs based on my overall muscle tone. I still have the saggy skin but its not that bad and you can at least see definition in my arms and legs and such when I'm doing things so it's a bit better to have it tighter. I wish I had started earlier. There are some weight training exercises that really provide a pretty good full body workout. For me, a personal trainer has been priceless. I would sooner give up my cell phone than her at this point.
