In-Line Skating and 30 Days Shred questions.

Littlefutureskinnylady

Hey there!
I want to ask you a few things. You'll see, I got bored of my gym workouts so I started to do in-line skating. I skate for not less than 2 hours a day , everyday and I keep increasing time and speed every week (I passed from 14 km/h to 16 km/h). Since the month is about to end, I want to combine skating with Jillian Michael's 30 day shred since August 1st.
My goal is to pass from a 25,5% fat percentage from my hips to something like 10-15% (I guess I didn't mention I'm trying to model). I passed from 30%-25,5% from 15th May to 15th July doing my normal workout which combined no more than 1.5 hours of cardio a day and a bit strengh training.
My question is...Is in-line skating better than elliptical and running when we talk about fat burn and tonning? And what about Jillian Michael's 30 Day Shred? How much time could it take me? (This question is dumb, but I'm started to feel upset about it )
Thanks a lot my beautiful weight loss friends !
