Thank you for viewing. This is a great value set of 2. Hand Grip with Counter - Grip Strength Training Equipment. This is grip strength training equipment with a counter. It can be used for training in all kinds of sports. It is highly effective for grip strength training in sports such as baseball, tennis, badminton, basketball, and free climbing. The load can be widely adjusted from 10 to 60 kg, so it can be used not only for men's strength training but also for dieting, fitness, and rehabilitation. Also, grip strength training is perfect for relieving stress when you are irritated or stressed. Especially, the red color of the handle allows you to devote yourself to passionate training. It has a counter that can measure up to 99 times, which will encourage your daily progress and serve as a guide for keeping records. By turning the adjustment dial clockwise, you can increase the grip strength, and by turning it counterclockwise, you can decrease the grip strength. The grip part (the part that touches the palm and fingers) is made of rubber material, so it is designed not to slip even if you sweat. It is compact and easy to carry, and you can start training immediately whenever you feel like it, wherever you are. We recommend keeping it in front of you while watching TV to make it a habit. How to train: ① To increase the strength of your grip itself, it is said that you can increase your strength by using a load of 85% to 100% of your grip strength and reducing the number of repetitions. ② If you want to strengthen your endurance, reduce the load and repeat the exercise with a high number of repetitions. ③ It can also be used for rehabilitation, which involves the actions of gripping, grasping, and moving your fingers.
