My scale

After my last scale gave up the ghost, I needed to buy another one. Fortunately, I found a good one on It was supposed to be around $75 but I got it for $35 and was happy to get such a bargain.

Now I don't really understand all of the readings, and I have read that in particular the body fat readings are not totally accurate (only to within a couple percent, not to the tenth of the percent they show it to). However, they do give you a general idea of trend (are you gaining or losing), and are in the ballpark.

One of my favorite things about the scale is that it keeps track of your measurements -- what they were yesterday, a week ago, 30 days ago, and 90 days ago -- so that you can see whether you're improving, declining, or maintaining your position in each of the categories you measure. Here are my 90 day readings from the scale.

Weight - down almost 13 lbs; another 85 or so to go -- definitely headed in the right direction!!

Body fat - down almost 3% (which is significant when you realize that I am losing weight, and the weight that I am losing is mostly fat, not lean muscle mass). I would like to get to about 20% body fat, which is somewhere between fit and athlete level.

Muscle - up 1.3% (some could be new muscle, but it is likely that I am just maintaining muscle mass and its relative proportion increases as I lose weight -- trying to unbury my gun show)

As an engineer, I am totally a number/metrics girl. I don't take it to Sheryl's level with spreadsheets or anything (though in the future I may up my game to do that), but I do love understanding what the numbers mean and keeping track of them to make sure they're headed in the right direction.

  1. Side note, I know you asked about this a while ago in terms of how long it takes to grow muscle. Not that this is a perfect source but I was listening to the radio the other day and the DJ was talking about his journey with the PX90 videos or whatever and mentioned that it takes approximately 6 weeks to gain muscle mass. Does that sound right to what you found out?
