Attention Laptop Nation: Do you slouch? Spoiler: You slouch. We spend so much time hunched over our laptops like fairytale goblins—and our backs are the ones doing the suffering. I’ve heard amazing things about the Upright GO posture trainer, and started using it about two weeks ago. So far, it's worked wonders for my less-than-perfect desk posture. It’s a small device that adheres to your upper back (it lays perfectly under a shirt so no one will know it's there) and vibrates to remind you to sit up straight. An app tracks your progress and gives you feedback. Straight up, I’m super into this.
