I did Cathe's Tubrobarre Premix Lower Body Express. This is one with her lower body that focuses on the legs. Cathe's Fit Tower is amazing! It is so much better then my plastic chair! Like I said, I am 5'8" , so I put mine to a 9, and I can still do her exercises. Yes, I have to adjust to it, but that is with any equipment. There is one part where Cathe's says you can put your head on the bar and then lift the leg. I was able to do it and see her on the screen. I had to be careful because the barre was high, but you can see what is done.
Cathe's Tubrobarre she ranks as a 5.5. I can understand somewhat because there isn't that much cardio to it, but the leg exercises are still hard. They will fry your legs. I don't know how Cathe and her crew does it. Your legs will be one fire! Even though Cathe label says it is Low Impact, don't be fooled, it is intense! Not much, jumping up and down, but a slow burning of muscles!
As for the Fit Tower, I should have bought it a year ago. It is worth the money. The barre is so comfortable. My plastic chair was rocky and unstable. The Fit Tower is very safe and it is stable. You don't have to do Cathe's workouts either. This Fit Tower is great for anything! Five Stars out of Five Stars!
