Ever notice your elbow or forearm feels tight and achy by the end of a work day — even though you didn’t “do” anything physical?
Here’s what’s actually going on. Every time you type, use a mouse, or grip your phone, you’re using the muscles that close your hand — your finger flexors. On a desk job, they’re working non-stop, all day.
The muscles that do the opposite job — opening your hand, your finger extensors — barely get used. And that imbalance between a hand that’s constantly closing and never opening is a real contributor to elbow pain, like tennis elbow or golfer’s elbow.
The fix is surprisingly simple and cheap: loop a rubber band around your fingers and thumb, then open your hand against the resistance. One set of 20-30 reps, done multiple times a day — you can do it right at your desk between typing tasks.
If you’re already dealing with ongoing elbow or wrist pain, get it checked out first — this is a prevention exercise, not a treatment for an existing injury, although sometimes it can be.
Give it a go this weekend and let me know in the comments if you feel that “opening” burn — it’s a strange spot to feel one for the first time. 😁🤲🏼
