Hi Sue,

First off, given the low acceleration of the crazy fit, it is unlikely that you can do any major harm. This machine is a massager for the most part. Having that been said, since the right THR was in 2011, you are working within one year post-op (unless it was January?). The general rule for vibration is that you begin training after 1 year post-op.

One of the reasons is that this is a typical timeframe for substantial healing to take place with this surgery (or any orthopedic surgery for that matter). You describe “knocking”, which is a rather vague description of your symptoms. Using my PT background, I would interpret this as a sense of instability. If this is the case, it may just be that muscles are not trained well enough yet and the ligaments require more time to stabilize the new hip. These are normal things for the most part and require time.

On the other end of things, given the nature of the surgery, if you feel any instability, it is important to also look out for substantial pain or even an intuitive sense that something is “wrong”. These both warrant trip back to the MD.

My advice, as long as you are not feeling severe pain or having any abnormal sensation when you are not on the platform, is to bring your feet in closer and keep the knees bent a bit. This will reduce the motion of the hip/pelvis while still stimulating the spine and muscles of the legs.

Hope that helps.

i had a left full hip replacement 25th august 2010 then the same on my right in 2011, i have used my crazy fit machine but i dont know if i should. the numbers go from 1-20, i feel it does work but with my right hip i can feel it knocking, its not uncomfortable but i dont know if i’m doing any damage because of the vibration. i go upto nub 8 as it feels safe to me. i want to use it more as this also feels good with circulation, would you beable to tell me if its safe to use every day because thats what. i dont ever regret buying this product. whilst i waitng for my oporations i used it a lot as it eased back pain and helped to keep me mobile, so i can say they do work , thank you for your time.

Hi Natalie,

It looks like they do a half decent job of promoting the specs, though here is my educated guess on the real specs…
The motors are almost certainly only 0.75hp each or less, the pivotal (tilting) specs would be accurate, and the lineal (circular) specs might be accurate when unloaded, but when you stand on the machine the amplitude will reduce to around 1mm.

As to the benefits they claim…..

Here is the list taken from their website:
Fight cellulite
Injury recovery
Relaxation
Increased metabolism
Pain dampening
Increased circulation
Increased bone density
Increased muscle strength
Increased flexibility
Improved coordination
Reduced body fat

I’d reduce it to:
Fight cellulite (may provide some benefit via cellulite massage in lineal mode)
Injury recovery
Relaxation
Pain dampening (potentially for some people, with some conditions, although mostly this is anecdotal)
Increased circulation
Increased bone density
Increased muscle strength (minimal rehab benefits)
Increased flexibility
Improved coordination

Provided you are aware of this, and don’t have expectations of more than this, you could do much worse for the $695 I saw advertised on their website. Please note that I have no idea as to the manufacturing quality of this machine.

Hi, I’m from Perth, Western Australia. I have seen an advertisement for a RenoufHome Fitness Vibration Machine VPR 9 BODYSHAPER. I am curious about whether it is worth looking at. The advert states the machine has:
“Two motors, two movements … Both “Tilting” and “Circular” in the one machine.
Having two movements in the one machine allows you to better focus on either Toning, Increasing bone density, Blood circulation or Coordination.
•Two motors 1.5hp each
•Tilting movement Amplitude: 0-10mm
•Tilting movement Frequency: 5-15HZ
•Circular movement Amplitude: 0-2mm
•Circular movement Frequency: 15-40Hz
•Three Pre-set Exercise Programs
•Speed range levels 1-50
•Steel Frame and upright post
•Input: AC220-240V/50HZ
•Product weight: 31kg
•12 month warranty”
My Mum and I are both considering using it. How would these spec’s help in the health benefits they claim?

The crazy fit is a weak, cheap pivotal platform that is unlikely to provide any additional benefits to regular exercises done without a platform. Consider it a really large, expensive massager. Good for circulation and perhaps balance training. Don’t waste your $$$$.

Does this machine really work and you can lose weight?

Unfortunately Will, you have to purchase both machines to experience the differences in manufacturing quality. Also, the differences in performance. This is why Murray of Hypervibe ha spent so much time and money having engineers test other platforms. The only platform to perform as indicated (like the Hypervibe) is the Galileo.

I believe the results of the Nitrofit engineering test will be available soon. Thanks for the post.

Purchased a Hypervibe recently and wow…quite a powerful showing. Was able to get a Nitrofit at a significant discount a month after my Hypervibe purchase, but Im left more with questions than answers. My understanding is that both platforms are manufactured at the same facility in China with manufacturing specs of the companies who order them. By all accounts, both products look nearly identical. Nitrofit advertises a max 30hz and max 13mm displacement, whereas Hypervibe claims 28hz max and 11mm displacement. As such, I had assumed that Nitrofit would be a slightly faster and more powerful machine. However, the Nitrofit, when I set it at its max speed of 30, felt about half the output of the Hypervibe at its max speed…how can there be such a huge discrepancy if Nitrofit has a purported higher max frequency and displacement? Is this a “misrepresentation” of their true outputs? Reported my concerns to the rep at Nitrofit and he wrote back: “The machines are produced in the same plant and should function similarly.” No…they don’t. Do you have any true measurements of the Nitrofit’s output as you have on other machines? Thanks!

Hi HJ,

These are an embarrasment to the fitness industry and of absolutely no value.
