If you want to know your lean mass percentage and other cool metrics about your body composition, the DEXA scan is one of the easiest ways you can find out.
The DEXA (Dual-Energy X-Ray Absorptiometry) is a fairly accurate way of measuring your body composition. This includes your bone mineral density as well as your lean body mass and fat mass.
The DEXA scan does this by exposing you to low level x-ray beams throughout your body while you lie on a table. There are few items of interest that the DEXA reveals. One is the lean mass versus fat mass percentage per region (head, arms legs etc..), the other is the bone report that tells you your bone mineral density per region.
I got my scans done at BodySpec, where you can get a scan for 45.00 or 2 scans for 85.00. You can also get your Vo2 max measured as well as your resting metabolic rate (RMR)
I’ve done this 2 years in a row. For consistency, both times I’ve done it was around the same time of day and in a fasted state.
Here are the results:
