The reset mechanism is strict in movement and on one hand it should be in order to prevent you from going in the wrong position and getting injured, on the other hand it is somewhat difficult to use. I didn't use it more than 4-5 times for this reason unfortunately, and it's not worth the cost even though the construction is decent in quality.

I expected it to have a reset system, which helps you return the body to its original position...! It doesn't have it. Chinese product, with instructions in Chinese. It appears to be a sturdy product. Maybe I should have bought something more expensive.

I am not an expert in sports, it seems sturdy, only time will tell. I tried it and felt my body immediately relaxing. I weigh 130 kilograms, so it definitely withstands my weight. And yes, what it has for the knees is simply useless, keep in mind something else instead of that. If I don't update and complain, it will be good :P

Must !! Ergonomics, durability under body weight (my own body .. 1.90) good materials. It works from the first moment you feel it and then you are hooked and in muscles you didn't know existed !!! :) :)

+ Good abdominal workout.
+ Good quality (although plastic) and size for a large-bodied man.
+ Strong resistance to sliding for assistance during movement (springs).
+ Comfortable handles for large hands at an angle that is convenient during movement, withstand weight as they are made of metal on the inside.

~The connection of the handles to the wheel is made at the bottom of the handles, and the metal is held in the rest of the perimeter covered by the thick plastic of the handles.

- The "knee pad" is a simple, low-quality foam. No resemblance to the image.

CAUTION: If your waist hurts even a little, you are doing it wrong and there is a risk of injury. I made the mistake the first time and it felt strange to me. I watched a video on YouTube and realized my mistake.

If you want to lose weight from the belly area, there is no quicker way...
I have had it in my possession for a month now and I use it daily with incredible results...!!

Very effective exercise for the core area with results even after a few days...

Very user-friendly and I am very satisfied. It is compact and doesn't get damaged when used vigorously, and it also has a knee cushion. It has convenient handles for exercises and is made with an internal spring that helps with repetitions. Perfect product.
