The HXGN Adjustable Grip Trainer is ideal for targeting the hand and forearm muscles which are important for improving grip strength. This gripper features a solid metal spring that can be easily adjusted to change the tension to suit your personal training goals. It provides adjustable resistance from 10kg to 40kg, allowing you to increase the difficulty as you progress your grip strength.. Increasing hand and forearm muscle endurance is vital for achieving heavier lifts and greater reps and helps ensure you won’t be let down by the limits of your grip. The adjustable grip has rubberised handles letting you achieve a stronger grip and it also has a durable moulded frame.
