I'm trying something similar last week and this week. As much as it surprised people at my meeting when I said it, I have a hard time getting all my points in, never mind flexpoints. I usually only touch the flexpoints if I go out to eat.
So last week I made sure I did my target and tried to get some flexpoints in. I also did low impact aerobics 4 days last week, rather than get on my Healthrider for 20 minutes. I would have done more, but pulled a muscle and took a couple of days off to let it rest.
Well, this past weigh in yesterday I only lost .2 which was a disappointment, but also something I know is going to take time, in that you won't see a difference in just one week, especially with getting a more rigorous workout.
So this week I'm trying to add in more flexpoints. I've also gone back to my week one booklet and trying to make sure that I get more protein in as well. I'm terrible with milk (other than cheese!) so I got the WW smoothie mix to see if I can get my milk in that way.
We'll see how it goes next weigh in... I'll let you know!
