Day to day I use a home body composition scale (Withings Body Scan), the results of which have been corroborated by two Dexascans I've done at my gym a little less than a year apart.

For me personally, the little bit of help in the form of forward progress on weight loss has given me a reason to be a little more methodical in my strength training, and I'm seeing a slow but consistent payoff. And as far as I can tell, I'm not fighting an uphill battle in terms of adding muscle mass at all because of the GLP-1.
