I have been using a exercise machinecalled a Chi Machine.
It moves your body much like the movement of a fish swimming.
It helps people who have a hard time doing standard exercise movements. Here is a short video to see how the machine moves.
Some of positions are shown below:
The Chi Health Device is best used on an empty stomach. Many people prefer to use it before breakfast and at night to assist deep sleep. Please use a room where you won't be disturbed—no phone or kids (soft music is OK). Hard floor with a carpet is best. Place device on floor and plug in. Put a towel over the ankle rests to cushion your ankle bones (if you need to) feet should hang past the ankle rests just enough so they will flop gently back and forth once the machine is turned on. Arms loosely at your sides, palms down. Do not use a pillow under your head, as this hinders the machine's motion from reaching your head. The footrest will begin to move back and forth, carrying your feet briskly from side to side. This movement will carry up through your legs and torso, and throughout your entire body; causing you to wiggle back and forth—that's right, just like a goldfish swimming in water. Once a timer is set the machine will begin to rock gently back and forth. As it does, your job will be to relax and "surrender" as much as possible and breathe deeply. This will allow the massage session to oxygenate your body. IMPORTANT! WHEN THE MACHINE STOPS, LAY STILL for at least 30 seconds and breathe deeply. This is the time when the movement of healing Chi energy is felt circulating throughout the body.
