Need Firm recommendation
 

I've been doing cardio and free weight training for almost a year now and am intruiged with everyone's raves about The Firm workouts. I already have the Ultimate Fat-Burning Workout, which I find mildly challenging.

Which workouts would you recommend for overall toning (I have plenty of cardio workouts)? I would like something really challenging! :carrot:

I don't think that any of the new Firms fall into the category of 'really challenging'.

Slim Series with heavier weights than Debbie uses? Now THAT's really challenging.

Cathe? Really challenging.
