Hi Marnski,
How are you?
I have read your previous post listing your rotation from your trainer as a reply to my question. The weight load is pretty heavy. I am sorry to hear you did not get what you were looking for. I suggest you carry on and eventually try both free weight at home and machines at Gym. I am not sure you have time to go to the gym. High rep workout (Barre workout are high rep light weight...) are not going to help you build defined and toned legs. If you are a hard gainer, meaning you find it hard to build muscle, keep cardio to a minimum cause you need to send a CLEAR message to your body!
I would confidently suggest you keep circuit to a minimum i.e once per week. It is just not the best approach for building muscles regardless of the the natural ability to build muscle or not, regardless of the body type (somatic body type ectomorph, mesomorph or endomorph)
Here is something for you to read should you wish to:

I noticed you did not mention cardio. Is there any reason?
I found you post interesting. Slimming the thighs is usually what women are looking. This is not the case of you
It is certainly not the case of some of us
All the very best and please keep us posted,
