I once sat for seven straight hours editing video. When I finally stood up, my right leg had gone numb from the hip down. I limped around the apartment for ten minutes waiting for feeling to come back, genuinely worried I’d done permanent damage.

That was the day I got serious about the “stand every hour” thing.

Why it matters

After about 60 minutes of sitting, your metabolism slows and blood pools in your legs. The enzyme that breaks down blood fats (lipoprotein lipase) drops by about 90%. Your spine compresses. Your hip flexors shorten. None of this feels dramatic in the moment, which is exactly the problem — you don’t notice until something hurts.

A standing desk helps but doesn’t fix everything. Standing still for hours has its own problems. The real goal is movement, not just posture change.

The trick: associate standing with something you already do

Water. Drink a full glass of water every hour. You’ll need to get up to refill it and to use the bathroom. The hydration is a bonus. This is the simplest system and the one I’ve stuck with the longest.

Every time you hit send on an email, stand up. If you send 20 emails a day, that’s 20 stand-ups. Don’t just rise — walk to the kitchen and back. Thirty seconds of movement resets the sitting clock.

Use a physical timer. Not an app. A cheap kitchen timer you set for 55 minutes and place across the room. When it beeps, you have to get up to silence it. Apps get swiped away. A beeping noise you can’t reach is impossible to ignore.

What to do when you stand

You don’t need a routine. Touch your toes, roll your shoulders, walk to the farthest room in your house and back. Twenty seconds is enough. The point is to break the sitting streak — the body resets the negative processes once you move.

I haven’t had a numb leg since. The bar is low, but I’ll take it.
