Does sitting on a fitness ball at a desk all day provide major health advantages?

just sitting on the ball wont give you any advantages but if you secure it by putting a large object(a chair maybe) behind itand try a few moves on it(listed in the manual)

it will not give u HUGE benefits but its good for ur body and u may even see some differences. id say go for it but dont expect to see a major difference

I mean.. i would think it would help improve your balance and maybe posture since you have no real support, its all your strength..
