The present application relates to the technical field of fitness equipment, in particular to a fitness action detection guiding
robot, which comprises a frame, the frame surrounds a space for performing fitness actions, a
horizontal bar is slidably installed on the frame in the vertical direction, a constant resistance unit for increasing static load of the
horizontal bar by applying unidirectional rotation resistance is arranged on the bottom of the frame and connected with the
horizontal bar, a reset device for pulling down the horizontal bar is arranged in the constant resistance unit, a hovering unit for controlling safe hovering of the horizontal bar is arranged on the frame, and a
data processing unit for indirectly detecting force time and force amplitude of
weight lifting actions is arranged on the frame. The structure for converting
linear motion into rotary motion is arranged on the horizontal bar, the constant resistance unit is arranged on the rotary motion structure, the
simulation of
core strength training of fitness actions is realized, and the constant resistance unit only applies unidirectional static load to the horizontal bar, thereby avoiding the risk of straining or crushing the user of the horizontal bar.
