Exercise does not counteract the effects of passive sitting
Cutting edge actual Science has found that sedentary behaviour shortens your telomeres (you know, the connective ends of your chromosomes) and, the shorter your telomeres, the older your cell age, and the more you're at risk for health complications.
To quote the New York Times, 'Reducing sedentary time had lengthened telomeres the scientists concluded, while exercising had played little roll... In fact the volunteers in the exercise group who had worked out the most during the past six months tended now to have slightly less lengthening and even some shortening.'
So, if you sit, the only way to keep your cells young and healthy, is to sit actively.
The only way to sit on an exercise ball
The Språng Chair builds on the key benefits of sitting on a ball by itself – core engagement, and movement – in so many ways.
Comfort - The Språng Chair's contoured seat, triple-cushioned with 3 different densities of foam, distributes your weight evenly (and breathes, unlike a rubber ball).
Lumbar Support - With the fully articulated, spring-loaded back, slouching and poor posture become a thing of the past.
Posture - Due to the way the seat tilts over the ball, acting like a fulcrum and opening the pelvic angle, everyone who sits on the Språng Chair rediscovers their body's natural good posture. It was there all along! (Whereas most people find the exercise ball alone is pretty much a slouch-machine).
Balance - The seat is a combination of stable and unstable -- unstable enough that you're mindfully (and proprioceptively) aware that you're sitting. Yet, it’s so well balanced that you can lift your legs off the floor and do little crunches, right from your desk.
Active Movement - The bungee cords work on the same principal as resistance bands, offering something to push and pull against. Plus the Språng chair is effectively pre-tensioned, so that movement in any direction activates a natural inclination to push and pull against the springy tension.
