Have you noticed that your face is angled downward at your desk or maybe upward? The ideal position is to keep everything in our bodies neutral.
If you took a snapshot of yourself right now, and you were to imagine the curvature of your spine, your neck and everything else.. would it be neutral? If it would, you’re golden. But if it wouldn’t then you should look into things like a laptop stand to keep you in a good position.
For me this included my chair, and I’m currently working on keeping my midsection tight after I noticed it was affecting my posture. This is still a work in progress for me, you can read my review on a wobble cushion here.
Posture sneaks up on you, like it did to me, so preventative measures are a good idea!
