This is a sturdy and durable ab machine. Good for the price. The inclination of the bench can be adjusted. However, I have two issues. 1) The bench cannot be adjusted perfectly horizontal. For people with big abs, this would be a problem. A wider range of inclination would be better.2) The bench could be longer. For people with long torsos the bench is too short.Other than that, I have got used to the inclination. It is a good purchase
