Sit in an uncomfortable chair Nowadays there are so many big, luxurious office chairs that are not only allowing but encouraging bad posture and low back pain! The more comfortable the chair is, the more apt you are to recline back and kind of sink into the cushions.

• If you sit on a wooden chair with a flat seat and an uncomfortable back (maybe just for a few hours to start), you will be forced to engage your abs (see the tip below for how to do this) and sit straighter without slouching.
  You will also become more aware of your posture because at first, this hard chair will be uncomfortable.
  

Pull your naval IN towards your spine, like you're zipping a tight pair of pants ABS IN! This is the number one reducer for low back pain.
A tight core, especially while sitting for long periods of time, will transform how your low back feels.

• Act like you are zipping a tight pair of pants, or like someone is punching you in the stomach and you're trying to pull away from that punch.
  Basically this is the Pilates way to engage your core and low abs.
  You can go to a Pilates class, or just do this at work at your desk!

Stretch the front of your chest Ever feel like a hunchback at your desk?

• Roll your shoulders back and clasp your hands behind your back.
  Stick your chest forward and reach your hands and arms back, away from your back.
  
• For a bonus, do this while pulling your abs in!
