Totally agree with Kat Trish. I have both and the EA Active is far better in terms of fitness. I actually find it better without the board as I can use it wearing sneakers.
When we lived in Darwin last year I lost 5 kilos in a couple of months walking and using it.
I have extra dumbells and step height for mine too, but I do go to the gym and find that on it's own it isn't much of a challenge.

eta I hate side lunges too Kat - always delete them!
