Biggest Loser TV show questions

[PRINCESS VIJA]

I love watching this show! They seem to have these super long workouts. How much time do you think they spend every day exercising? They must do some outrageous amounts for contestants to loose so much weight every week. So what are your guesses? How much are they exercising?

I could be wrong but I thought I read 4-6 hours. But it included low intensity things as well.
