The following is the information I found. AD abdominal muscle fitness equipment has eight functions: sweating metabolism, strengthening function, eliminating fatigue, beautifying and slimming, supplementing exercise, activating cells, dredging meridians and strengthening functions! It took me about a month, and my waistline decreased so quickly. It's amazing! There will be no side effects. Losing weight means more exercise, and more exercise can reduce it. I bought it from Euroblueprint. com. It feels good. You can go and have a look. If it is good, choose the best answer for me. Thank you.
