1, roller diameter: the larger the diameter, the lower the exercise intensity; conversely, the smaller the diameter, the greater the exercise intensity. For beginners, it is recommended to choose a roller with a diameter greater than 15cm.
2. Material of the drum: At present, the drum with good quality on the market is made of PVC, which has the advantages of low noise, wear resistance and difficult deformation.
3. Width of the roller: The wider the roller, the easier it is to exercise, so it is recommended to choose a thick roller or a double-roller belly wheel. A good belly wheel will also adopt floating-point anti-skid design on the gear to achieve anti-skid and shock-proof effect.
4. Strength of steel tube: Steel tube is the main stress component of the abdominal wheel, which directly affects the durability. High-quality steel and thickening can make the abdominal wheel safer and more durable. However, if the steel material is poor and the thickness is thin, the bearing capacity will be relatively poor, and it is easy to bend or even move when used.
5, handle design: a good handle will generally be wrapped in a thick layer of foam, which can play a very good anti-slip and sweat-absorbing effect.
