The equipment needed to track certain measurements accurately for long has been out of reach due to cost. Nowadays, though, as it usually goes, we have innovations that make technology more affordable. This is the case with cameras and infrared sensing devices. Just look at almost every house with a teenager and you'll find a Kinect for Xbox One. While it's great for gaming, that same Kinect has been modified for medical and other uses far beyond video games.
The advances in that field have also lead to a new device called the Shapescale. This device will be available starting in our office in April. What it is able to do, is precisely weigh you while also taking hundreds of pictures from a rotating camera. The accuracy of the camera allows it to determine where your lean mass, fat mass, and body composition changes occur. So if your goal is weight loss, and after working out for months, you have only lost a few pounds, this tool can show you precisely how your body has reshaped itself instead. You could always track this yourself by measuring your body parts, but that can be difficult. This scan automatically measures all of your body parts in under one minute.
You hear all the time how working out doesn't always lead to weight loss, but it will change your body fat and muscle percentage. Now you can prove that. Have a scan done now, and then have a follow up scan 2-6 months down the road. Now you will have definitive proof that your hard work, is working for you.
