track body 

A body type usually seen with people who participate in track and field. It is thin, toned body that may make the person appear weak but is really hiding their incredible athleticism. This can consist of muscular legs, a six pack, and well defined arms. People with this body mainly compete in distance, sprinting, and jumping events. These body types are usually underestimated by members of other sports teams.

Body Trace 

In raving or glowsticking, it is the act of "tracing" your body in different ways, stomach tracing is the act of tracing your stomach. There are all different ways such as tracing legs, arms, or head.

I can body trace perfectly after practicing it.
