Speaking of body and muscle the place I go to has a InBody analysis machine. The results give a picture of your body health very interesting. I found it helpful and showed I was doing all the right stuff. The test result categories are:
Body Compensation analysis
-Total water body
-Dry lean mass
-body fat mass
-weight
Muscle-Fat analysis
-weight
-skeletal muscle mass
-body fat mass
Obesity analysis
-Body mass index
-Percent body fat
Segmental Lean analysis
-left arm vs right arm
-left leg vs right leg
-trunk (body core)
