After much anticipation, I finally got my Turbo Fire DVDs yesterday. Did my first "class" this morning, and it did not disappoint! I love Turbo Jam, so I had high expectations. It is definitely intense (I looked like someone had dumped a bucket of water on my head afterwards) but it is also super FUN! According to my HRM, I burned almost 400 calories during the 30 minute workout. I saw someone on a difference message board say that they burned around 900 calories with the hour long (or 50 minute - I forget) DVD. Anyway, I'm actually looking forward to working out now, and just wanted to share my enthusiasm :-)
