AI Technical Summary

Problems solved by technology

However, there are certain shortcomings in this method: (1) Before each sit-up, it takes a certain amount of time to find a weight-bearing block with a suitable weight from the surroundings for training to increase the weight

(2) The original use of the weight block is not necessarily held in the hand, so its appearance is not necessarily clean. Holding it in the hand may stain the hands of the trainer, which is not conducive to the continued training later

(3) Hold the weight block with your hands for training, and its safety cannot be guaranteed

(4) This kind of weight training, whether it is to put the weight on the chest or behind the head, will make the person or the neck lean forward, which will add extra load to the person's spine or cervical spine, and easily cause the trainer to be injured
