The product is perfect in all aspects and i and my family members are loving it. Everyone is using it and it does work perfectly on your abs. If you have fats like me around your abs, you can trim them down by burning it out.
Put the pad under your knees and you can do it before a wall so that you can stretch up to the wall and retract back. That is how i do it and start with 2-3 mins and extend that to 10 mins. The construction is sturdy and hence, you do not ahve to worry about any aspect.
However, it is not suitable for those who have had any major surgery.
Finally I found Best Abs Roller... Really nice product.. I used to be very fat and searching for good exercise for abs exercise. I found the abs Roller, honestly it's really easy to install and very impressive. I am doing exercises from last 6 days untill arrived feel like my belly tummy goes inside fast. It's really worth its to buy . Material quality is also good Special a person those who really fed up with heavy exercise of abs. For me and them best option is abs Roller. I am highly Impressive with this product. And the price is also not so high.
I have used a lot of rollers before but the overall quality of this is unprecedented , this is also true because of its traction with any surface the only downside I feel is that the price could be little lower
