In the industrial world, Passive Sitting has become the main daily activity, averaging 10-13 hours a day between work and home.
Medical researchers have long warned that prolonged sitting is dangerous, associated with a significantly higher risk of:
— heart disease,
— diabetes,
— obesity,
— depression,
— back pain.
Sitting has become a ‘new smoking’. 
Research has shown that during passive sitting we have a higher loading pressure inside the spinal discs, compared to standing or walking.
Sitting contributes to deconditioning and earlier development of spinal degeneration, disc herniation and chronic back pain.
According to recent research sponsored by the Bill and Melinda Gates Foundation, back pain has become the leading cause of disability in the world, affecting nearly 1 in 10 people, and becoming more common with increasing age. In the US, an estimated 65-80% of the population will suffer from LBP at some time in their life. The total estimated direct medical costs associated with the treatment of back pain is about $86 billion per year. An estimated 149 million work days are lost every year because of LBP. The total costs (including lost wages and lower productivity), estimated to be up to 200 billion a year. It is the leading cause of disability in Americans under 45 years of age. Solution 
In order to keep the spine healthy, one has to maintain back and core strength, flexibility and good posture.
Exercise is very important in order to strengthen the abdominal, para-spinal and pelvic musculature. When muscles in these areas are stronger, they can take pressure off the spine and help prevent back injuries.
Now this can be easily archived while sitting at your desk or at home, but in a new, DYNAMIC way, while strengthening your body with the ActiveFitnessChair.
The chair trains your posture, and helps you to strengthen your spinal muscles, core muscles, gluts and quads, and prompts you to sit actively, while still at work or home, gaining fitness and health, rather than losing it.
It helps to increase metabolism, lose calories, improve circulation and bone mineral density (which is especially important for older people).
Dynamic resistance recline. 
This can be done while doing any desk work except for typing or writing. From an upright position move the back of the chair backwards while it is sliding with your spine braised against the back support. The angle of recline can be either full or partial. Doing the full recline promotes a better workout, and allows unloading of the spine from the vertical compression forces.
Frequency and Resistance settings: 
If doing 10 repetitive reclines seems too easy, change the resistance setting until you feel mild to moderate effort during the recline in your spinal and core muscles. Repeat 10 reclines minimum 3-6 times per hour. If you feel soreness of the muscles next day, do not increase either the resistance or number of sets the following day. Change of the resistance setting has to be very gradual, once per week, or so. Maximize the number of reps during the day/week first, before changing the force setting.
Posture Training mode, or Isometric (motionless) resistance. 
Designed to allow any types of usual desk work, including typing, writing etc. This mode assists in reminding the user to sit in a better way at the desk, training proprioception senses of the body and spine. While sitting in a chair, turn the switch, which will bring the back of the chair and your spine forward twenty degrees, than actively engage your spine to push the chair back into a vertical position (the vibration reminder sensor will be automatically ignited until the back is in the optimal vertical position range). This mode allows ACTIVE SITTING in a motionless way, promoting strengthening of spinal postural muscles, core muscles, gluts, pelvic and thigh muscles. Use this mode as frequently as you can, starting at five min. on, five min. off intervals. Later on, sit in this mode until you start feeling muscle fatigue, at which point you have to stop. Build endurance gradually.
Regular passive chair 
used as a regular office chair.
For the past five years our team of scientists, engineers and ergonomic specialists 
have been working on creating an innovative concept of a new office chair. 
Our ActiveFitnessChair can help people who sit at work to feel 
and to look better by building a strong back, beautiful posture and a flat stomach.
