Build functional forearm power and wrist stability with precisely calibrated hydraulic resistance that adapts to your current strength level.
-
Customizable Resistance Range: Adjust the tension dial from 8 lbs to 15 lbs (3.6 kg–6.8 kg) using a marked scale where guiding toward 5 increases the assist level and guiding toward 1 decreases it.
-
Durable Cast Iron Core: The heavy-duty hydraulic pump delivers consistent tension throughout every rotation without sudden slack or mechanical failure.
-
Targeted Rotational Training: Designed to isolate forearm, wrist, and grip muscles through controlled twisting motions that improve your daily lifting capacity and sports performance.
-
Ready-to-Use Setup: Includes an English instruction manual to guide you through safe resistance levels and proper form from day one.
