Lower fixing rotation core strength training and quantization monitoring device

The utility model discloses a lower fixing rotation core strength training and quantization monitoring device, and relates to a strength training and quantization monitoring device. The problems that a special lower fixing rotation core strength training device does not exist, and quantization monitoring even cannot be conducted on motion parameters are solved. The cambered surface of a balance seat is in rotating connection with a base, a chassis is fixedly arranged on the upper end face of the balance seat, and a pedal is arranged over the chassis. The pedal is connected with the chassis through a fixing shaft which is vertically arranged, the upper end of the fixing shaft is fixedly connected with the lower end face of the pedal, and the lower end of the fixing shaft is fixedly connected with the chassis. A shaft sleeve is arranged on the fixing shaft at the lower end of the pedal in a sleeved mode. A rotating resistance device is mounted between the fixing shaft and the shaft sleeve, the lower end of a ro
