This thing rocks. Had an ab roller for quite the while, this steps it up 10 fold. Fantastic

This is awesome. You can engage your core in so many different ways - and you 100% know it is working as you feel pretty sore afterwards.

Works my core like nothing I've done before. Gonna get these results in no time!

I love it, when I use the product it maintains and strengthens my core I know I will see great results after a few months. I recommend this core tool to anyone.

Very durable and effective workout device. Helps the core muscles real good. Have been using it on and off for last year or so.

I’m very pleased with this product. Works like they said it did. Thank you.

CoreFlex 4D is the best product of its nature hands down. I will be 62 this Month on the 28th. So I've seen the early models of the wheel in the beginning stages. That put a lot of stress and pressure on your wrist area. The CoreFlex has been a game changer since day one....
And what's even better than the product is the customer service! I reached out with an issue of how can I fixed this and they made it right immediately with than a few days.
Thank you CoreFlex 4D for all yo do, I'm a customer for life😂💪🏾

Well made device, easy to use. Resting on the elbow supports makes for the possibility of more time under tension.

I was skeptical at first because I have tried multiple ab rollers in the past. They always led to shoulder pain and stopped working after a while. After I got the core flex all that changed, my shoulders don't hurt anymore whole using the core flex and it has fixed some core instability I had. There are so many exercises that can be done and I enjoy the challenge again. I'm excited to useI was skeptical at first because I have tried multiple ab rollers in the past.
