As we all know there are no pills to make you better, healthier, nor smarter, even if every ad tried to sell health in a quick and easy format.
This is what I like form these exercises, they are just meant to realign your posture.
That being said you'll still have to work at it, but its starting point .
and really if it can decrease the stress, even by 10%, on any of your joints, your body will do the rest. Our bodies ALWAYS seek homeostasis.
