Here's a handy little fitness fact that has slipped under the radar for decades - you actually can't "flex" your muscles!
The term flexion applies to only your joints (1) and not your muscles.
Muscles do not flex or extend, they only contract or lengthen.
You can't "flex" a muscle per se, you can only shorten it!
But still the term sounds awesome and you'll never remove it from pop culture (and nor would you want to!)
However, just a little bit of information you could remember to show off next time someone asks you to "flex."
Then of course, make sure you "flex" the house down for them!
So why is it called Fit'n'Flexed?!
Well....because FIt'n'Contract doesn't quite have the same ring to it!
There's also no alliteration either....
I trust you'll forgive me for it!
