Thanks- and interestingly, others have told me for a while that they suspect the center's scales are measuring me too high. I missed a recent opportunity to do a BodPod measurement but they will be back to my club at the end of the summer, so maybe I will try it then for more accuracy.
I do strength train, once a week with a trainer who pushes me hard, then two-three other more times on my own, alternating an upper and a lower body. I am too pressed for time to do upper amd lower on the same day, so i do about 20 min of walk/jog intervals on a treadmill, then about 35 minutes of strength, plus a little stretching. However I am not very systematic, and this makes me think it would pay off to keep records and really work to challenge the weights. Often I don't really remember what I did last time.
Meanwhile I will stay on MetaBalance another month. It sounds like the combination of diet and strength training will be helpful. Thanks Gina!
