a little disappointed

Duffeyl2

So I have started alternating workouts at the gym where I run 2-3 miles and 30 day shred because as a nurse working nights there are some days I cannot get to the gym. But I am a little disappointed in the 30 day shred calorie burn. I plugged it in and it only gave me 150 calories. I can burn double that at the gym running for only 10 more minutes than the dvd gives me.
