Imagine holding a plank all day. Sitting upright and holding your spine straight all day is no different! At some point, instead of getting stronger, those muscles are going to fatigue and get weak and tight!
That’s why I ALWAYS prescribe this exercise to 95% of my clients.
It will FINALLY let those poor back muscles relax!
The body simply loves movement VARIABILITY. That’s why the body doesn’t respond well to lots of sitting OR lots of standing. Neither is inherently bad, but it’s the lack of movement, and the over-abundance of the same posture.
I’ll even let you in on a little secret:
The best posture is the posture that changes most often.
I suggest shifting around in your chair and changing positions at least every 10 minutes! And yes, that should absolutely include a bit of slouching to give your back a rest!
So next time someone’s giving you a hard time at the office for having bad posture, let them in on the secret too - you actually have great posture!
