Product Details Features Highly Resilient Precision Steel The Hand Grip Strengthener is made from high-quality precision steel. This steel composition has excellent elasticity, allowing it to provide effective resistance for hand and finger exercises. The excellent elasticity ensures that each squeeze optimally engages the hand and finger muscles, promoting strength development and improved flexibility. Whether you are performing repetitive squeezes to build endurance or performing single intense contractions to achieve maximum strength, the highly resilient steel adapts to your efforts. Electronic Counting and Timing This Hand Grip Strengthener is equipped with an electronic counting and timing feature that allows you to easily monitor your progress. You can set specific workout durations, which is essential for structuring your training. For example, you can set 30-second intervals for intense gripping, followed by 15 seconds of rest, and repeat this cycle for a set period of time. The counting feature helps you keep track of repetitions, allowing you to measure your progress over time. This feature is invaluable for those who are looking to set and achieve specific fitness goals related to hand strength. Durable and Sturdy Construction The handles are designed with durability in mind. Its sturdy construction can withstand the rigors of high-intensity workouts. The materials used provide sufficient strength to ensure that the handles will not deform or break under continuous and vigorous use. This sturdiness means that you can rely on the handles for long-term training, whether you are a casual fitness enthusiast or a professional athlete who uses the equipment for heavy-duty use. Wear-resistant, rust-free, and non-breaking These handles are made of high-quality materials and are highly wear-resistant. They can withstand long-term and intense use without showing signs of excessive wear. The non-rusting property is particularly beneficial because it ensures that the handles maintain their performance and appearance even when exposed to sweat or used in a humid environment. The non-breaking design guarantees safety during use and prevents any potential accidents caused by breakage. Ergonomic TPR handles The handles adopt an ergonomically designed TPR (thermoplastic rubber) handle. The shape of the handle is carefully designed to fit each finger comfortably, providing a firm and stable grip. This ergonomic design not only improves the comfort of use, but also reduces the risk of the handle slipping during exercise. As a result, you can focus more on your exercise and don't have to spend too much energy to maintain your grip, thereby improving your training efficiency. Wide Resistance Range These handles offer a wide range of resistance levels, adjustable from 10KG (22 lbs) to 120KG (264 lbs). This wide range is suitable for users of all strength levels. Beginners can start with lower resistance settings to gradually build up their hand strength and get used to the exercise. More advanced users can challenge themselves with higher resistance levels to further enhance their grip strength for rock climbing, weightlifting, or sports that require a strong grip.
