Thank you for viewing my listing among many others. (*^^*) [Product Description] This product allows for two types of training with one ab roller and one push-up bar. Although not mentioned in the instructions, you can also perform butterfly training by opening sideways from a push-up position, which targets the inner chest muscles. (^^) It is perfect for dieting and building muscle in preparation for the height of summer. The bar is designed to be smaller than the insertion hole to prevent it from coming out, so please insert it all the way in. As this is an overseas product, there may be slight differences in minor scratches, color, etc. It will be shipped in simple packaging. Thank you for your consideration. (^-^)
