We mumble for one simple reason. We’re being lazy with our mouths.

Let’s be honest, most of us don’t use our full vocal toolbox. We underuse our lips, our tongue barely moves and the words blur together making it hard for people to follow what we’re saying.

That’s all mumbling is: Lazy articulation.

But the good news is, just like training your guns in the gym, you can train the articulation muscles in your face 

The Tongue Twister Method (With a Twist)

One of the most powerful daily exercises I recommend is simple: tongue twisters.

But here’s the twist, don’t rush through them.

Spend 10 minutes a day reading tongue twisters slowly, deliberately, and with exaggerated mouth movements. Overdo it. Move your lips wide. Get your tongue involved. Let your face feel ridiculous (that’s the point!).

By doing this, you’re training the tiny articulating muscles in your face, lips, and tongue which are responsible for shaping every word you say.

It might feel strange at first and you might even laugh at yourself.

But if you stick with it, you’ll start noticing that the unfamiliar becomes familiar and you’ll be much less likely to mumble when you speak.
