A ground-based rotational training device that works the entire body. Perform explosive 1- and 2-arm movements and other rotational exercises simply by inserting any Olympic-size bar (not included) into the 12" pivoting sleeve at the units base. A 4" sleeve is also available to hold standard 1" bars. Combine with the Landmine Handle for work that targets the shoulders, core, and hips. Connector pivots side to side and top to bottom.
