Logging my exercise question????

I do a 50 minute class at my gym of light aerobics for 15 or so minutes and then there are different exercises - either using a band, light weights or body bar plus abdominal exercises - what do I log as - I've never done slimnastics or jazzercise so I don't know what that is... it is definitely a hard class - please help me to figure out how to log it????
