1.5-Piece Complete Set for Comprehensive Hand & Forearm TrainingIncludes an adjustable grip strengthener (11-132 Lbs/5-60kg) plus 4 complementary tools (e.g., finger trainer, grip ball, wrist roller, finger stretcher), covering grip, finger, wrist, and forearm training. One set replaces multiple single tools for all-around hand fitness. 2.Wide-Range Adjustable Gripper for All UsersThe core adjustable gripper features a dial to switch resistance from 11 Lbs (5kg) to 132 Lbs (60kg). Ideal for beginners (building basic grip), athletes (boosting sports performance), seniors (maintaining strength), and those in post-injury rehab (gentle recovery). 3.Dual Focus: Muscle Building & RehabilitationHigh-resistance settings (66-132 Lbs/30-60kg) help build hand and forearm muscle mass, enhancing strength for weightlifting, golf, or rock climbing. Low-resistance options (11-33 Lbs/5-15kg) support post-injury rehab (carpal tunnel, wrist sprains) by improving mobility without strain. 4.Ergonomic & Durable Design for Long-Term UseAll tools have non-slip, soft rubber handles that fit small to large hands, preventing slippage and discomfort. The adjustable gripper uses heavy-duty metal springs to maintain consistent resistance; other tools are made of wear-resistant materials (eco-rubber, reinforced plastic) for durability. 5.Portable for On-the-Go TrainingEach piece is compact (palm-sized or smaller) and lightweight, fitting easily into gym bags, pockets, or desk drawers. Train while commuting, working, watching TV, or traveling—turn idle time into effective hand and forearm workouts, no bulky equipment needed.
