Built to develop grip strength, the adidas Adjustable Grip Trainer specifically targets the forearms and hand muscles. Featuring a solid metal spring and durably moulded frame, the Grip Trainer allows you to increase not only the strength of these muscles but also your muscular endurance, helping you to reach heavier lifts and greater reps without your grip letting you down. Designed with a unique adjustable mechanism, the Grip Trainer can be tuned from 10 40 kg of resistance. The Trainer's tension dial helps to avoid training plateaus and allows you to continue to develop your grip strength as you progress. The Adjustable Grip Trainer also features rubberised handles for a stronger grip when applying maximum pressure. | adidas Unisex Adjustable Grip Trainer 10-40kg in Red | Size: 40kg
