I've been coming to Knockout fitness in Surprise for 4 months. Here is what I think. I joined mostly for the kickboxing and boxing classes. The class schedule is good. They have many classes and many times during the week.
The instructors are skilled and qualified. I wish they would give some explanation at the beginning of each class on proper form so people don't hurt their joints. Be warned, in my opinion the music is TOO loud during the class. This makes it difficult to here the instructor. Several times my ears were ringing after class. It is also hard to concentrate for those around not in the class.
The weight area is small and needs a little more expansion. It's very basic and a little small so you have to wait if there is more that 4 people using the weights.
There is a jujutsu area that I have not experienced yet. But I have observed that the instructors are good. The kids classes are also great.
The staff is pretty friendly and helpful. I notice there is some turn around over the couple of months I've been here. But that is expected in this industry. They also have other locations the instructors seem to rotate through. Instructors I prefer are CJ and Ty (pronounced Tee)
You can borrow boxing gloves if you need some. They offer personal training that is worth the price.
The membership is pricey, but honestly if you utilize the group kickboxing/boxing/jujutsu classes, you get your monies worth. Don't be afraid of trying them.
Overall people are there to work out, are friendly. I would recommend this place for those who are actually going to work out.
