Creating and maintaining good posture
decreases your risk of developing back problems.
Achieving comfortable, good posture
will provide a functional range of movement
that will allow you to perform daily activities safely.
Even if your back feels OK at the movement,
you may be straining it if you:
Have poor posture.
Move your body incorrectly.
Are out of shape or overweight.
All of these strains add up until one day
a simple act like bending over can bring on back pain.
When correctly aligned the back has three curves.
It curves in (forward) at your neck (1),
out in the chest region (2),
and in again in the lower back (3).
These curves help distribute pressure evenly
throughout the vertebrae and discs.
Body mechanics is defined as
the way in which you move your body and back.
Good body mechanics includes
lifting loads close to your body
to reduce strain on your back
and maintaining your three natural curves
to keep your back in balance
