Designers: that flat drawing tablet is quietly wrecking your neck. Looking down at a Cintiq or iPad can load your spine like a 40-60 lb weight - the designer version of tech neck.

Anterior pelvic tilt is the most over-diagnosed posture problem online.

Most pain-free adults have a forward-tilted pelvis - it's normal, not a fault. And a 2020 review found weak evidence exercise fixes the angle.

When it matters: https://t.co/gsD6JXuygF

Most "kyphosis from sitting" is muscular, not bony. Tight chest, weak upper back, 8+ hours of desk geometry holding you in flexion.

A 2019 meta-analysis (10 RCTs, 457 ppl) found 8-12 weeks of strengthening reverses it. Self-tests + protocol:

Quick test: arms relaxed at your sides. Thumbs pointing inward, backs of hands forward? Rounded shoulders.

73-78% of desk workers have it. Pec minor tight, mid/lower traps weak. 2023 RCT: 4 weeks of daily home exercise alone reverses it.

Forward head posture: ears in front of shoulders, deep flexors weak. A 2024 RCT moved the average craniovertebral angle 44°→50° in 4 weeks.

Tilt your head 30° to read your phone and your cervical spine sees ~40 lb of effective load. The fixes aren't complicated - geometry, breaks, chin tucks - the hard part is noticing.

What's an AI posture app actually doing when it tells you "you're slouching"?

Pose model finds your joints. Angles measure forward head. Calibration learns *your* posture. Smoothing decides when to ping.

That's it.

"Ergonomic desk setup" guides read like shopping lists. You don't need any of it.

The geometry that matters:
- Eyes level with top of screen
- Elbows at 100-110°
- Feet flat
- Monitor an arm's length away

Stack of books works fine.

Sit up.
That's it. That's the post.
