A 1.2 mm thick steel pipe with a firm abdominal roller + non-slip handle of PP material + tires of TPR material are adopted, making it stronger and more stable. With the 18.5cm wheel, core training can be performed, and abdominal muscles training can be performed at a position closer to the floor. Abdominal muscle roller is recommended if you want to break your abdomen at home training.
The abdominal muscle roller with a two-wheel design supports the force of the built-in spring in the correct movement direction when contracting the abdominal muscles, so it can be used safely by beginners and those who easily hurt their back. Two kinds of modes can be adjusted. The wide type is stable mode and easy to balance for beginners. The short type can firmly train the trunk for advanced users.
