12 minute plank – cardio style interval workout

by purelytwins

Plank cardio workout that only takes 12 minutes. Shed fat around your midsection with this fun home workout.



You all know we adore our planks. And love making fun interval style workouts with them. We love doing planks almost daily to help ensure even ab development and planks help with having our abs display muscle tone. Planks are great for adding in some definition to your stomach without adding bulk.

Today we have another 12 minute interval plank cardio workout video.

Make sure to see our first 12 minute plank workout video too.


The workout is made up of two 6 minute intervals.

New to plank: make sure to watch some of our other plank workouts videos to get other ideas of where to start.



Need to set your Gymboss Interval Timer for 6 rounds of intervals of 30 seconds and 30 seconds.

First 6 rounds you will be doing low plank and high knees.  Back and forth for the 6 minutes.

Second 6 rounds you will be doing low plank and side lunge jumps. Back and forth for the 6 minutes.

This quick workout is great doing on it’s own or adding it to another workout of yours. Remember to go at your own pace and but push yourself.

The more you push yourself and get out of your comfort zone the more changes you will see in your body!

You can put some music on while you do this workout to help get you fired up 🙂



Get strong core #purelytwins way!

Remember to tag us instagram to let us know you did it!

And one question we get asked often is can you do planks everyday? 

Short version: YES! But you don’t have to.

Long version: Planks don’t damage the muscle as much as other ab exercises so making it okay to do everyday. Planks train your abs to be in a controlled state when your spine is in a neutral position. So you can do planks everyday if you want since it doesn’t tear down  your muscles.

Happy Planking!

See you in the next workout.

You guys rock! I’ve been doing your plank workouts for a few months now and have been finding them easier and easier (but NOT easy)! Progress!

I am wondering…you both have such defined abs and arm muscles…is your primary workout planking or do you use weights often to get that definition?

purelytwins January 11, 2013 - 5:02 pm

awesome Sorayya! so happy to hear this, keep up the great work!! We feel doing planks just about every day has definitely helped with define our arms and abs more, in addition to doing weights, HIIT workouts, and lots of push-ups.
