AI Technical Summary

Problems solved by technology

[0003] Sitting forward bending is one of the main movements of leg ligament training, but because sitting forward bending training will produce a huge soreness, such soreness will drive the trainer's body to bend forward insufficiently, and the persistence time is too short to reach To achieve a good training effect, it generally requires artificial assistance to press down on the back

However, training cannot be accompanied by someone every time, so an auxiliary device is needed to assist in sitting and forward bending
