Accurate Activity Levels

Hello all! I am also new to this site and have found some phenomenal information through these message boards so I figured I would ask a fitness related question....thank you in advance for your advice!

My question has to do with activity levels as I'm getting quite confused in terms of what is classified as "light" or "moderate" activity. On the Scooby site "light" is 1-3 hrs/week of light and "moderate" is 3-5 hrs/week of moderate exercise.

Before I thought that I would be in the moderate range but after reading some of the posts here I'm second guessing myself. This is generally my workout regime....any help or advice would be great

Monday and Wednesday - 1 hour Zumba or alternate cardio (JM Banish Fast Boost Metabolism/treadmill)
Tuesday,Thursday, Saturday - Jillian Michaels Ripped in 30 plus 30-40 minutes treadmill, either interval training or fast walk on incline
Friday - Jillian Michaels Banish Fat Boost Metabolism 40 min and sometimes an additional 30 min treadmill.
Sunday - rest day

Should I be using "light" or "moderate" when figuring my TDEE? Thank you again!
