Problems solved by technology
[0002] In the gym, although you can see a variety of abdominal muscle training methods, it is difficult to see a combination of equipment specifically for abdominal muscle training. Ordinary people who have not been in contact with fitness can only do it through supine crunches or planks. Support and other methods to train the abdominal muscles, these existing fitness methods can not focus the force on the abdomen well, so even if the method is specially used for abdominal muscle training, it will also make the training difficult because of the non-standard training actions. The effect is greatly reduced
