what is 4D dynamic core training?

Boring and ineffective static planks and ordinary crunches are a thing of the past!

By taking the traditional Plank and elevating it off the ground onto a single pivot point, the CoreFlex4D adds a new dimension of movement, angles, and instability to the traditional abs & core workouts, making maintaining balance more challenging, and stimulating more muscles more effectively for more time - essentially super-charging your abs & core workouts!

Each 4D Dynamic Core workout improves your core strength, stability and balance, burns more calories, and boosts metabolism.

The Fundamentals of 4D Dynamic Core Training

- Stability Planks -

Static Plank, Active Plank

Adds an element of instability to the traditional static plank, to engage more core muscles. Upgrade by adding active movements such as Mountain Climbers or Horizontal Jumping Jacks.

- Dynamic Planks -

Twist, Tilt, Lean

Get a 360° core workout and increase difficulty by turning the static plank into a dynamic exercise - by Twisting, Tilting or Leaning to both sides. 

- Rolling -

Straight, Angled

Utilize and upgrade Ab Roller functionality to get a full motion workout, by extending straight forward and to the sides and retracting back.

How Does It Work?

MORE Exercises, MORE Engaged Muscles, A MORE Effective Workout - For that 'COMPLETE 6-PACK' Look - Faster Than Ever Before

Forget everything you know about Abs & Core workouts, because the CoreFlex4D is completely Re-inventing them.

The CoreFlex4D's patented design with a Single Dynamic Pivot Point - a single touchpoint with the ground that can move to all directions - is what's behind the CoreFlex4D's three main advantages over any other ab trainer or abs & core workout available today, and the reason it is the only Abs & Core trainer that gets you that Complete 6-Pack look, fast:

MORE EXERCISE VARIETY - BETTER MUSCLE ACTIVATION FOR BETTER RESULTS

The CoreFlex4D's unique design introduces a wide variety of new, innovative, extra-effective exercises to your abs & core routine, such as Twists, Tilts, Leans, Crawls, and many many more - resulting in significantly better muscle stimulation and a more interesting and less mundane workout for you.

CONSTANT 360° MUSCLE ACTIVATION - ENGAGE THE ENTIRE CORE 

The CoreFlex4D's design puts the body in a constant unstable state "forcing" it to work (hard) at stabilizing itself.

So whichever exercise you're doing on the CoreFlex4D, your abs & core work first and foremost to stabilize your body, resulting in a constant 360° activation of the entirecore muscles. 

NATURAL MUSCLE STIMULATION - FOR A MORE EFFECTIVE WORKOUT

The activation of the Core muscles when the body is stabilizing itself is more natural compared to the artificial motion of an exercise, because it is essentially what the core muscles were meant to do - stabilize the body.

This results in better, more complete, and healthier muscle engagement, directly leading to better and faster results.

Eliminates Pressure and Strain on wrists, shoulders, and back

As opposed to a traditional ab wheel, the CoreFlex4D is designed to transition the strain and pressure from the wrists, shoulders and back, to the forearms, for a comfortable, pain-free workout, in which you are free to focus on form and range of movement rather than pain and discomfort.

When a movement is done correctly, the muscles are stimulated better, muscle flexibility is improved, and overall results are achieved faster and with less strain on the rest of the body.

Targets the Core, Engages the Entire Body

From your shoulders and arms, through your abs, obliques, and back, and all the way to your glutes and legs - CoreFlex4D upgrades the traditional Plank position to engage your entire body, for a quick and extra-effective daily workout.

All you need is just 3 minutes a day

Thanks to the way the CoreFlex4D effectively engages the abs & core muscles consistently and from all angles, all it takes is a short daily workout of only a few minutes to start feeling your abs get stronger and more toned.

So so

So the functionality of the roller is good just not the price. I bought this thing (isn’t cheap) and no workouts came with it. No instructional video or link. With the price a workout should come with it

Hi Timothy. Every order of the CoreFlex4D includes our free training 'The Fundamentals of 4D Dynamic Core Training' in which we explain and demonstrate all the main exercises with the CoreFlex4D, and additional tips and techniques from our head trainer. We can't find your order number (perhaps it was ordered under a different name), so if you did not get the link to download this training with your order please contact us with your order number at support@masteryourcore.com and we'll look into this.

Best ab workout

I am 220 and consider myself out of shape. Been doing coreflex4d everyday for 5 days now and my abs are really sore but a lot tighter than usual. I do this to finish out my workout for the day. I can only do the regular rolling and on my knees for now but i can tell that i am getting stronger and eventually would be able to do the more advance moves. This also hits your triceps as well as your back which i love as well. I will do this everyday until i am back in shape. Goal is to loose 20-30 lbs.

Working core in multi dimensions

Super happy with CoreFlex 4D!!
Very humbling because it really exposes weak movements and allows you to really hit them.
I’m finding that a short workout with CF4 gets more done than all the core work I previously did. Looking forward to developing more with this great tool!!

It’s a beast.

I used a standard wheel for a while. I recently upgraded to this product and I love it. Easier on my shoulders. Allows focus on the core. Love it.
