Uh yeah. I've been jumping between 169 and 166 since May.
Just keep at it. Maybe switch up your exercise. While I haven't lost any weight, I've gotten a bunch smaller, so I just say keep with it. You could try calorie cycling, as well.
I was stuck at 168 for months, when I was doing the same workout routine. I was shrinking but the scale hated me. I stopped working out for 2 months and dropped down to 158...shocking for me as well I know. But of course I slacked at my diet so I'm up 5 pounds again over the wonderful holidays...
What ever it is your doing try something different.
This happens to me all the time. I will stall at the same couple of pound range, and then I will have a good week and lose a couple. You do have to switch things up. Try eating a bit more for a day or two, and then drop your calories. This can trick your body and up your metabolism. Just stick with it. Being stuck beats gaining any day!
