It's been 2 weeks and have dropped 38lbs. I feel great and ready to do sit-ups and and run, but not sure how long I should wait since it's only been 2weeks since the vertical sleeve surgery??

Everyone will have different advice based on their doctor's instructions.

That being said my Dr. told me to get started day 1. I started walking the day of surgery and have kept going longer and further as the days went on. I strongly believe getting up and moving helped my recovery versus sitting on the couch.

I even asked about weights and he said between the stitches and glue there was little risk of pulling/tearing something. I thought was a little odd since I had been reading here that most Dr. said wait 6 weeks for weights. I chose to wait 3 weeks before lifting again. When I started I went light and have been building on that.

Do what you feel comfortable with.
