I&#x27;m reasonably fit, but I&#x27;d never stood for the whole day, until two weeks ago. Then I started running the family business while the parents went away for vacation. I decided to stand &#x2F; walk instead of grabbing a stool because I thought it would compensate for the lack of other exercise I&#x27;d be getting - business hours are fairly long, and I really don&#x27;t feel like workout out after.<p>Take-aways so far:<p>- When standing, I automatically change it up - sometimes I stand up-right, sometimes I stand with my legs split a bit.<p>- After a couple of days of discomfort, I can basically stand all day, no issues.<p>- I come home, and sit. And if I&#x27;m watching TV, I pass out for a good 20 minutes. Automatic nap.<p>- I don&#x27;t feel sleepy at work at all. Zero lethargy. I don&#x27;t feel sleepy after lunch.<p>Some advice:<p>- Try to engage your core, your glutes, legs.. different muscles to keep you upright.<p>- Change things up. I try not to lurch. To lower myself, I split my legs a bit. Sometimes for fun (while reading email, random junk online..) I do a half-squat.
