The Abdominal and Core Trainer Mat by 321 STRONG is a well designed and constructed device to help tighten and strengthen obliques and ab muscles. I walk daily and do a variety of fitness and aerobic exercises but tend to shy away from core concentration on my stomach. One reason is that a lot of ab work involves sit-ups that place strain on the lower back.
With a little practice, I’ve found the mat is a great cushion that greatly reduces lumbar strain, and makes crunches and sit-ups much less painful. All you need to do is take a few moments to position the mat cushion and then let it help provide support for your routine. If unfamiliar with the basics, the mat has exercise picture instructions printed on the back with QR codes that link to live instructional videos via a smart phone.
The product arrived as scheduled. The mat is constructed of high intensity foam bound in black vinyl. The mat includes a lifetime warranty and 100% Satisfaction Guarantee.
I appreciate that the seller, 321 STRONG, contacted me with useful information prior to testing. "Testing" the product refers to the fact that I received this product at a discount in exchange for my honest and unbiased review.
I highly recommend the 321 STRONG Abdominal and Core Trainer Mat as a high end and useful product.

Reasonably priced and quality product. Fits my needs as a pantry light 100%

I saw something like this at a hotel gym and it was very useful for ab exercises. This does the job and gives you the right leverage to do multiple types of ab exercises. Also good for stretching when I have lower back tightness. Really enjoy the product and communications from the company gives me the sense that they are out to make great products and provide support. I did receive this product at a discount in exchange for my honest and unbiased review.

Exactly what I was hoping for! A very sturdy product.

I put it in the RV bathroom because the kids can't reach the overhead lights. The white is not blueish, but it is a very cold white. The warm looked too yellow. There is more than enough light for midnight trips. I do wish the auto shutoff timer was adjustable. 15 seconds can leave you sitting in the dark, albeit momentarily.

I need about 10 more of them for the cabinets to replace all the tap lights we put in.
