All these are very inaccurate. To get the nearest numbers you need to get those good ones, which cost about RM500~RM1K, they have this thing to hold to measure your whole body. That one also give and take, not 100% accurate.

I threw away all these weigh machines by the way, cause it was making me depressed. I just continue with my workout regimes no matter what and recently im starting to see the results, took 5 months of consistency though! And getting rid of the weigh machines help a lot.

you will see that a lot of professionals will tell you to get rid of the weigh machines when you start working out. cause the numbers will fluctuate like crazy and to many people it's discouraging, which it was for me. And i got rid of it and just continued with my workout and take care of my food.  Only recently i see the results, not numbers but obvious changes on my body and how i feel overall. and that for me it's a win!
