Hi Karie,
I've only been doing barre workouts for about a month or two but I haven't been exclusively doing the Physique 57 (I've had the DVDs since 7/31 and do them an average of 3-4 times a week...sometimes more) DVDs. I need variety so I do mix them with Pure Barre and Fluidity... and whatever cardio that suits my mood that week.
I can't attribute all my results to "just one set" of DVDs, but in general I can say I've noticed more definition in my torso and legs as well as a higher rounder seat. I'm a little surprised because I never thought I could achieve these results without heavy weights. In general, I'm really pleased.
I haven't noticed any weight loss and to be honest, it's simply not a goal of mine (I've basically been about the same weight since my teens). What I have noticed is a much firmer body....and yes, that is always a goal of mine.
I'm sure these types of workouts aren't for everyone (as you already know, there is no such thing as a one size fits all workout
), but they really are working wonderfully for me.
HTH,
