Multifunctional abdominal exercise wheel
The present invention discloses a multifunctional abdominal exercise wheel, comprising a main body, support members, a central pipe fitting, and a spring barrel. Two ends of the central pipe fitting are each provided with a support rotating member. The support rotating member is pivoted to a support member. The central pipe fitting is inserted into the spring barrel and fixed. The spring barrel is provided with a power spring. The main body is fixedly provided with a single-chip microcomputer, and a display apparatus, a sensor, and a button separately electrically connected to the single-chip microcomputer. Therefore, motion data can be displayed, the stroke and resistance of the abdominal exercise wheel can be adjusted, torsion outputs are stable, and springback noise is small.
