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.

Loving this thing

It’s taken some getting used to but absolutely loving the core flex. For me, I have found that it allows me to to get into a more comfortable position for planks (I have wrist pain) and you have a flexibility to tweak out your planks.

My new best friend

OK guys, I hope this wins me a side hustle writing marketing copy for you..

I haven’t been to a gym since Covid happened. It was fine for a while because I suddenly had the time to cycle 2 hours a day and that kept me in shape. I had to change work locations and jobs and ended up in a situation where I am in different places different days of the week. I really couldn’t justify joining a gym where I’d only have access a few days a week. I’m old enough to the point where it eventually caught up to me, and the worst place it affected me was in my gut. My growing dadbod was really pissing me off. I had made a resolve that I was going to get in shape somehow, and a friend sent me a link for coreflex 4D. It looked like a good idea so I bought it on a Sunday morning. It showed up the next day and as soon as I began using it I felt a difference in my abs and in my chest.
I was really excited that because of the flexibility and the range of exercises with just this small lightweight piece of equipment, it feels like I have a whole host of machines at my disposal. I can do strength, endurance, and even cardio on any floor, even a carpeted one. Depending on how its used one can really exercise most of the body in a way that doesn’t strain the back like situps often can.

The added bonus is that it affected my posture in a positive way, causing me to strengthen the chest muscles and and sort of pull at my breastbone. I am a semi-professional singer, and within two days I was able to increase my range because of the stretches and flexibility and positive posture reinforcement the coreflex was giving me.

I decided to start taking it to work with me and using it throughout the day to keep my energy up and just give me more time with it.

Then I discovered an additional bonus that I’m sure none of the designers ever conceived of. One of my jobs is as an audio mixer. It involves sitting in the same place for hours on end, not really being able to move your upper body because you can’t leave the sweet spot. I realized that the handholds and forearm rests can also support my feet. By placing the coreflex on the floor as a sat in my mixing position, I could put the heel where the forearms would go and the front of my foot where the hands grip and just sort of swivel or pivot with the music. This enabled me to keep motion and circulation going when I was otherwise just sitting, and really helps me stay awake if I’m doing too much mouse clicking.

So in short the CoreFlex is now one of my best friends and companions. If I can’t go to a gym or have the space or budget for a bunch of home equipment, I feel this one piece of equipment is really going to get me closer to where I’d like to be.
