I really liked it until the change to intensive 2. I live in a cramped flat and she was asking me to do stuff I don't have the space for, which is why I think I stopped both times.
That's good to hear you had an improvement though. I think I need to start up again and find a way to power on through to the end. Although I have aerobic fitness because I run, I have stopped doing any strength and toning work and am quite dismayed to find my core strength has almost disappeared. I swear it was so much easier to keep when I was younger!
