KEYWORD: VIBRATION TRAINER

Can you really get into shape just by shaking? Of course! A lot of exercise 
gyms have vibration trainers. Simply get on, hold tight, and off you go! You 
can select how much you want the  
machine to vibrate, based on your 
weight and training goals. The  
vibrations are conveyed to the  
muscles in your body and work to  
strengthen them. That’s how you  
can turn a vibrating motor into an  
exercise machine. 

What do shaking and 

exercise have in common?

YOU WILL NEED 

› The assembled exercise machine
› A few anchor pins and whatever bars you like

› 

3 x AAA batteries or 3 x AAA rechargeable batteries 

› 

A few small stones in a bag

HERE’S HOW

1.   Build your own exercise machine! You will find the 

instructions on the following page.

2.  Open the cover on the vibrating motor. That’s how you 

get to the battery compartments.

3.  Insert the batteries as indicated inside the 

compartments and replace the cover.

4.  Stick the bars together however you like, mount them 

on the vibrating motor, and switch on the vibrating 
motor. What happens to the bars?

5.  Now place the bag with the pebbles on the motor. What 

happens to it?

WHAT’S HAPPENING

In this experiment, you will clearly see how the 

vibrations move upward from the motor and 

become transferred to whatever objects are on 

top of it. The heavier the objects, the less they 

vibrate. Just be careful not to let them fall off the 

motor platform.

EXPERIMENT 6

TIP!

 

Your exercise 

machine will work 

best on a large, 

smooth surface.
