Freestanding boxing speed trainer combines a central punching bag, two speed spheres with 90° rebound springs, and a 360° rotating spinning bar so you can practice coordination, reaction time, and accuracy in one station. The 6-level adjustable height range lets different users in the household set a comfortable striking level. A widened base can be filled with water or sand and works with suction cups and a suspension system to help keep the frame stable during repeated training. Metal, ABS, and PU leather construction supports repeated strikes.
