Meet Torq-King: a handy tool that gives you a full-body workout anywhere. It lets you perform 360-degree exercises. The omni-wheel system gives you a lot of flexibility when performing moves. You can adjust your body position to further challenge your body.
If you like ab-rollers, you'll likely love the Torq King. It might even persuade you to leave ab-rollers altogether because they can only move forwards and backwards; the Torq King can move in all directions, which vastly expands the range of possible moves. Use it with your hands or feet and engage your core with every move.
