I was really excited to try this out. I liked the idea of being able to use the wall to help maintain posture. At first it feels really awkward for people who aren't used to squats because you have to extend your feet farther forward to prevent improper positioning of the knees. But it feels great when you're flowing through the movement.
I'm 5'4" and I feel like the bands don't engage until I am nearly fully extended. There would be more resistance for taller people. I would really like to be able to increase the resistance.
Backward lunges are much easier to do with this system because you don't lose your balance like you do with free weights. It doesn't hurt at all, but the links rest on my shin during the movement which is distracting to me. You can place it behind your leg, but then you have to use extra muscle to keep your heel planted. Be careful so it doesn't break free and flick you where it hurts most.
Also, the foam on the foot handles is very thin and flimsy. I don't see it lasting very long especially if you're wearing shoes. But you'll still be able to use the system even if the handles fall apart.
I loved the workout! I especially love the carrying case. I took it with me on vacation and it was perfect. It's small enough to fit in your luggage and you can assemble it in less than a minute. Just be sure to store it so that the foam rollers aren't compressed or else they become lopsided for a bit and you'll feel it when they're rolling along the wall.
I received this product complimentary in exchange for an honest trial and review. These are my personal opinions and experiences.
