Wii EA Active - More Workouts

Got the More Workouts wii for Xmas and I don't know if its because I've been eating too much without exercise or if this is more taxing, but after 19 mins do I feel like I've done a "huge" workout.

I set my own workout (as I did with the original one) and this game I feel has worked me more than the other one did, and I found that one difficult!

I've found it very challenging. I have VERY stiff quads at the mo! There seems to be alot more cardio, and there are an awful lot of squats even in the waterskiing. I do like the resistance exercises tho, they seem more effective than on the original. I like the boxing too, especially if you use the board as you have to use your legs.
