Question: Is this a horizontal or vertical plate vibration? Thanks!
Document: My BW requested a vibration machine for her birthday a few months ago. I purchased an expensive 2 motor, 2 vibration machine. These machines are more expensive and powerful and some can do see-saw plate vibration and linear plate vibration. We set it up in the bed room and my wife loves it and I certainly see results both in weight lose and muscle activity.
This machine increases blood and lymphatic circulation in the legs and whole body. Excellent therapeutic effects. Compact; lightweight. Only need to use it 10 minutes a day. Thanks for the speedy delivery.
And our local news station just covered the vibration craze! Super easy to use! Highly recommend, much more expensive elsewhere!
I love this vibration machine. I was about the buy the other plastic one, but thank God I didn't. This one is made of metal which will last long and works great.
This works well! It produces several rates of vibration so you can choose which best suits your particular health level and goals. It's too heavy for me to lift but thankfully it has a &#34;traveling&#34; handle which telescopes out so, you can move it even if you can't lift it. I find it comparable to the $3000 machine I was using at my chiropractors office.
The Soozier Mini Full Body Vibration Exercise Platform Machine  meets my expectations at 100%. The machine is strong, the vibrations are adjustable and can be set the type of function that you want to exercise. I recommend it because since the first time I used it I felt my muscles toned and my butt lifted!All my family are using it and them love it!
If you go up to 20 speed its crazy! If you are new at this go slow....I know you will think you can handle it, but believe me I have been doing vibration machine for over 6 months now and you will feel the pain in your leg's if you don't start slow! These machine's are the latest craze and they work! Remember, they say 10 minutes is equal to an hour at the gym!UPDATE:I have had this machine for a month now.
We bought this whole body vibration unit after doing a lot of research. It came in at a good price, and we have used it daily. It is quiet and powerful. The handle and wheels are nice for moving it around. The remote works perfectly. With isometrics and the vibration I'm pretty well convinced that it improves circulation and muscle tone. Make sure the unit is level and on a hard surface.
I have only had this vibration machine 1 1/2 weeks, but so far am loving it. I have been using it 10 minutes everyday and it seems to be making my legs stronger. (noticed this when going up stairs) I used Program 1 first week and now using program 2 for a week. I like having the bands attached it makes it easy to exercise your arms some while you are standing on it.
I wish I had bought this sooner. Three weeks after I bought and used this machine twice a day on a lower setting, I could zip up some knee boots that I purchased really cheap but could not zip up due to one leg being bigger than the other. Now I can zip both boots up with no problem. It gives me energy too. If I don't use this vibration machine, I'm tired for the day.
