Is fit barre, strength training?

Schtroumpfkin

As somebody of the "cardio is everything" generation, I realise I have to incorporate some strength training into my exercise. As much as I'd like to try, I can't do heavy lifting (don't have any weights/don't want to join a gym), so I was wondering if fit barre represented "own body strength training" and whether that was enough to get my muscles working off those calories....
Thanks!
