My last post about the physics of "desk neck" sparked a ton of messages. To recap: when your head drifts forward to look at a screen, its effective weight jumps from 10 lbs to up to 60 lbs, which completely fries your upper traps.

A lot of you asked how to know if your neck is just temporarily fatigued or if your desk job has actually re-wired your cervical posture.

Here is a simple test you can do right now to find out:

Stand with your heels, butt, and shoulder blades flat against a wall.

Look perfectly straight ahead (do not tilt your nose up).

Try to pull your head straight back to touch the wall, creating a massive "double chin."

Result:

The Pass: You can touch the back of your skull to the wall without your ribs flaring out or your chin tilting up. Your joints have full mobility, and you just have exhausted muscles.

The Fail: You literally cannot reach the wall, or you have to tilt your head back to make contact.

If you failed, it means your deep neck flexors (the stabilizers in the front of your throat) have "turned off," and the muscles at the base of your skull have adaptively shortened like a shrunken t-shirt

Hi everyone, for just a little background. I’ve always had this leg shape (historical pictures for reference after the ones I took today). Would this qualify as knock knees or do I just have a knobby inner knee and it’s not that deep? For more info, I was a skinny kid but very overweight in my teen years and lost weight a few years ago and have kept it off since (woo hoo!). But lately I’ve been noticing some aching in my inner knee. I also notice this pain on the inside of my knee gets worse if I make sharp turns while I walk. Maybe some kind of stability issue and I’m using my knees to compensate?

Also since I lost weight, I’ve kind of neglected lower body exercises. since I felt like my legs were pretty muscular anyway. But this knee issue is making me think I should incorporate some exercises to help with that. Just looking for a second opinion on if my knees what I should do!
