Bodybuilding & choosing a vibration machine -
When using a vibration machine or bodybuilding, I look for the machine with the highest accelerations and G force with the least ballistic impact to the body. The machines most people prefer for body building are either the high acceleration pivotal models that go over 20 hertz a second and tri-planers. Linear models are good but the slight side to side and front to back can help work the stabilizer muscles but not the ones that hit it too much to the side as our joints aren't made for lateral g force.
As long as there is enough vertical force to give enough G forces to help build muscle when weight loading, it should be enough to get the 10 to 15 minute workout that everyone claims they can get which is like an hour to an hour and a half in the gym. Fatiguing the muscles in 15 minutes which normally would take over an hour requires a much idffernet nutritional plan and joint support than a normal workout.
All of the body builders that use the vibration machines in these short workouts all take some kind of joint support supplement, as they say. The most common thing I hear is Glucosomine. Everyone using heavy weights on that is multiplied by the G force of the machine when standing on it, always tells me that you need to do something different than just what they did when normally working out. Almost all the people that buy tri-planers are bodybuilders. Unlike the chiropractors or physical therapy clinics who buy low acceleration pivotal models for rehabilitation, the tri-planers and high acceleration pivotals, I have gone to gym after gym and all I see are tri-planers in almost every gym. The more expensive gyms to join, like Equinox, has the tri-planers in their gyms in almost all their gyms. People actually wait in line to use it.
Deciding between a high acceleration pivotal or a linear vibraiton machine that has lower amplitude but quick acceleration levels is sometimes a hard choice but depending on what your current body type is and how advanced you are and how much G force you can handle helps to know which type to pick out.
Just about all the bodybuilder I have talked to always prefer one type over the other after trying a tri-planer and a high acceleration pivotal. Not many people can try both before they buy. The best thing I can say is, if you want my help, let me know what you want. Do you want to tone? Build bigger muscles? Workout with lower amplitude (2 to 6mm) on a faster moving linear or workout out with your feet moving 10 to 11mm up and down on a pivotal. Each has their own advantages and disadantages is all I will say without saying one is better than the other or trying to trash talk brands that might not work better. Both extremes are the Hypergravity.net models that go to 6mm in amplitude. That pretty much sets the standard in linear and they are made in California near Los Angeles. For the pivotals that go past 20 hertz, the Hypervibe model is the extreme in residential machines. I would not recommend the spiral machines if using it for weight loading bodybuilding exercise as the primary reason for spiral is rehabilitation and weight loss.
If buying one for bodybuilding, make sure that if you are doing heavy weight loading exercises and putting barbells on your back, for example, make sure the machine is built of steel and has enough power that the plate won't diminish acceleration and G force which can be affected by adding extra weight.
