GD Grip Strength Trainer (Premium Adjustable Grip Strengthener for Forearm Training) Wrist and Forearm Strengthener

This grip strengthener seems to be very well built. I have been using it for about a week with no issues. Here are a couple of comments based on other reviews, questions others had and some questions I had before buying it. Will this fit my hand? - I have smaller hands and I was concerned this would be difficult to use. Measuring from the bottom of your palm to the end of your middle finger, my "hand" is 6.5" in length. I have no issues gripping this. Sometimes, I find myself sliding the grip further down my fingers towards my palm. So, there is even a little extra room if your hand is smaller. It does get slightly bigger as you increase the resistance. It is about 0.25" wider (at the end of the handle) on it's hardest setting. How hard is this to grip / Can I use this or is it too hard to squeeze? - Yes, unless you classify yourself as very weak. I used to rock climb (not professionally or anything) but I haven't done that for years. I purchased this to use while I am watching TV, reading at work, etc to give me a little workout and improve my grip strength. I would say I have average strength (there are some pickle jars I can't open and reach for the rubber mat to improve grip). I am currently using this on the W setting, which is the lowest setting and I can complete about 30 reps with full travel of the grip (bottoming it out so the handles touch). Eventually, I expect to move up the scale, but I'm not looking to bulk up. Is this worth the price? - Bottom line, yes. It is pretty robustly built. It feels solid in your hand and doesn't feel cheap. I used to have one of the plastic 3 spring compression grippers and those feel cheap. The grip has a slotted pattern to it which keeps it lighter but retains strength/rigidity. If there's one weakness, it might be the strap. It is a standard cord strap that is found on most point and shoot cameras and could wear out over time. However, I don't really use it and may remove it entirely. This would be your preference. Does this make noise? - For the most part, no. I have held it up to my ear and I can hear a very, very faint click which occurs about 3/4 of the way through the travel when it is on the weakest setting. Turn up the resistance at all and the sound disappears. If I am holding this in my hand, in a comfortable, bent arm position, I can't hear it. It is only when it is about 8 inches from my ear that I can even perceive the sound. It is in no way obtrusive, distracting or a detraction from this product at all. Other grippers I have used creak and squeak during use. This does none of that. Bottom line, this is highly recommended and I would purchase it again. It is far better than the many of the other different styles of grippers I have used. As a bonus, the strap is reflective for when you're out running/walking in the dark and want to work on your grip strengthening.

I've had my GD Grip Ultra 70 exerciser for a little more than 6 years. It is very durable. I especially like how the grip handles stay parallel throughout the exercise. Both the resistance and the grip size are adjustable. The front black knob adjusts the resistance while the silver wheel adjusts the grip size. When the front knob is turned, the spring compression is changed, changing the resistance and moving the bolt forwards or backwards. That also moves the silver wheel the same distance which changes the grip width, which then must be readjusted. For instance, if the front black knob is adjusted 1/2 turn clockwise to increase resistance, that moves the bolt forward and compresses the spring. Then the silver wheel must also be turned 1/2 turn in the same direction to maintain the same grip width as before. Otherwise, increasing the resistance will decrease the grip width making it generally easier, while decreasing the resistance will increase the grip width which makes it generally more difficult. So, the key is to turn both the front knob and the silver wheel the same amount and in the same direction to keep the grip width the same while changing the resistance. Turning the silver wheel to widen the grip will also increase the resistance. This occurs because as the grip gets wider, the cam pressing against it to compress the spring moves horizontally and feels the full force of the spring. When the grip is narrower, the cam moves at a more downward angle giving a mechanical advantage over the wide grip when compressing the spring. It also means that as the grips move closer together, the required force to close the grips becomes less. So, the resistance level isn't linear over the full grip range, though this isn't obvious when using the device. Things that could be better: 1. The grips are hard plastic, and at higher resistance level might be a bit uncomfortable and a bit slippery. Workout gloves should help with comfort when needed and friction tape should help with slipperiness. 2. The front knob resistance adjustor doesn't stay set very well. It is just a nut on a bolt. When the grip is flexed, the nut moves forward and can easily turn on its own, changing the resistance. If you like to work with progressive resistance, that will undermine the effort. I wound Teflon thread tape around the bolt 15 or 20 times (it's thin) and then put the nut on. That gives it enough resistance to keep the nut/knob from turning on its own while still allowing it to turn easily for adjustment. I highly recommend this grip exerciser for its stable, parallel handles during use, and for its resistance and grip width adjustability. It has a wide range of resistance, though the lightest resistance might still be too strong for many women and boys.

Over the last year I purchased a few similar grip strength trainers and this is by far my favorite. it has a sturdy construction that feels nice in the hands, but the one feature that really sets it apart are the rubberized handles. The other ones like this that I have tried were just plastic or metal handles, and when I started using them for higher resistance, the grip would slip or it would get uncomfortable to use. The rubber grips add a little bit of cushioning and some grip so the trainer stays in the same spot in your hand your entire workout. This trainer has a button activated rep counter, which registers each rep when you fully compress the handle. Nothing earth shattering, but it works well. The trainer is also easily adjustable using a large metal dial and a smaller knob at the front to adjust spring tension and handle travel. My only wish for this would be more detailed resistance markings on the trainer. To determine the amount of resistance you need to count the number of dial and knob turns and note the position of the handle and compare it to a chart on the package to get a rough approximation of the amount of resistance you are dealing with. Overall this is a great option for a grip trainer. The spring give a consistent resistance throughout the pull, it is comfortable in your hands, and easy to adjust.

Very sturdy this thing is going to last. I was going to buy the cheaper ones you can get for seven and eight bucks but lots of reviews show them breaking so went for more expensive one and it was worth it

Best grip exerciser I have ever owned or seen. I’ve owned the simple kind with the big spring at the top. They only have one tension and grip length setting. So that’s the first plus. This one has adjustable tension and grip length. Other grippers have a single pivot point so most of the hand tension is on the fingers at the bottom of the grip. You can actually lift your index finger during exercise because it’s not getting worked as much. This gripper has a scissor action that puts the tension more evenly across all fingers. That’s the second big plus. There are lots of other adjustable tension grippers available. But look at the hinge at their pivot point. They all have minimally small pins through the hinge. This looks like the weak point to me or their smaller springs. This gripper has much more robust hinges and springs. That would be the third big plus. I found the handle surface to be a little smooth feeling at first. After using it for a while, my hand strength improved and I have no problem with the grip. The stresses on my fingers made them a little sore and I was wishing for a softer grip, but after a while my fingers toughened and it’s also not a problem. Man up. The grip is fine. I got one without instructions in English. I played with it and got frustrated and almost sent it back. Don’t do that. It’s not that hard. Here is what you need to know. Tension is the black knob on the front. The silver wheel is the grip width. It’s not exactly straightforward because one affects the other somewhat. Start here. Unscrew the front knob until it’s not engaging the frame. Then screw it back to just touching the frame. This is minimum tension. It’s also how you should store it when you’re not using it. The frame will bow if full tension is left on it all the time. (See pics in other reviews.) Now adjust the grip width. Open the grip to full open to take the pressure off the silver wheel. Spin the silver wheel toward the front (towards tension knob) as far as it will go. Then putting your hand on the gripper, figure out how far out you want the grip to open. Hold it there and spin the wheel back to touch your grip length position. Now your tension is at minimum and your grip length is set to your hand. Give it some squeezes. If it is too hard, shorten the grip length. If that’s still too hard, this one is not for you. If it’s not enough tension, squeeze the gripper to take tension off the tension knob. Then spin the knob in the direction of the arrow. I went one revolution at a time until it was too high and then backed off until it was just right. There is a hole and an arrow on the tension knob so you can count revolutions. If you move the tension very much, it will change the grip length and you will have to readjust that with the silver wheel. Don’t forget to open the grip to take the pressure off the wheel to make it easier to move. That’s it. Here is a tip. Remember how many revolutions of the tension knob to get to your setting. Always unscrew the tension knob to just touching the frame for storage. Then when you’re ready to use it, just spin the tension knob to your setting. Hope this helps you to like your GD 70 gripper as much as I like mine.

This is a really nice grip exerciser. I got the Korean version so no chart and everything is in millimeters and kilograms. However using 1 inch = 25.4 millimeters and 1 kg = 2.204 pounds it is and easy conversion. Now as far as setting the various resistance levels. There are two adjustments. The nose adjusts from 0 to 5 turns, and the metal ring adjusts the grip distance from 65mm to 85 mm over 8 turns. Using these two in the right combination allows you to pick resistances part way between to settings given on the chart. So with the nozzle set to zero, and the handles set to 65 mm/2.5 inches ( the metal ring is all the way forward), the chart says you need 20kg(44 pounds). If you move the nozzle to 1, reset the handle to 65 mm the chart says 23.5 kg (51.8 pounds) So by turning the nozzles only half way and resetting the handles to 65 mm you can get the intermediate 47 pounds. Likewise for a nozzle setting of 0 and handles at 65 mm were back at 44 pounds. Now if you set the handles to 75 mm which is approximately 4 turns of the metal ring you get 26 kg (57.3 pounds). so 57.3-44.0= 13 pounds. So each turn of the ring from 65 mm to 75 mm increases the grip resistance 13/4 pounds. So by judicious selection of grip width and nose settings you can reach a lot of intermediate poundage's when the jump on the chart is just too much. Please note: The pounds etc are not to the decimal point. So don't complain and do your own calculations if you need that kind of precision. Now: usage- These will definitely give you a good work out. I like to use a higher weight that limits me to maybe 20 reps, and then drop back to a lower weight and do another 60-80 reps. I like the parallelogram actions. I find at the widest grip setting it is sometimes difficult to completely close the handles without it wanting to turn in my hand. I wrapped the handles with rubber bands and that did seem to help some. They seem to be sturdily made and only time will tell how well they hold up.

Built. Like. A. Tank. Instructions on how to use this device, explained at the bottom. Pros: 1) Everytime you squeeze, all 4 of your fingers are exerting relatively the same amount of force due to the handles being almost parallel to each other from the resting position to fully squeezed position. This is extremely important because it allows me to train my fingers equally. Unlike other grip strengtheners where their handles are like gun triggers; when training at high strength, the index and middle fingers have to try their hardest to pull the handle in before the shorter ring and pinky fingers can assist in squeezing. As you can see, this causes fatigue before proper work has been done. 2) Adjustable handle spacing. I'm a 5'2" guy and my hands are rather small so this device made me extremely happy to be able to wrap the tip of my fingers around the handle and exercise. Unlike other non-adjustable strengtheners, my short fingers barely managed to wrap around the handle and have caused me much frustration and finger pain. 3) Macro and Micro adjustment of strengths. I couldn't read the Korean instructions but with half an hour of playing around, I've got the gist of using this device. INSTRUCTIONS BELOW. Cons 1) INSTRUCTION SUCKS! However, I understand because it's hard to explain the increase of strength on this device since there's no unit of measurement. _______________________________ Allow me to explain the two points of adjustments first before I explain how to use this device. A) The plastic black knob, located at the front, near the gold logo is the Macro adjustment knob. B) The shiny silver disc is for Micro adjustments. Let's say that for every full clockwise turn of the plastic black knob, the strength is increased by 20lbs and the silver knob can be rotated to from end to end to increase up to 10lbs. The silver disc, starting nearest to the black knob, as it travels further away, increases the strength. This also means that as the silver disc moves away from the black knob, the gap between the handles also widens. So you have to keep in mind of 3 variables, the gap of the handles to fit your hands, the macro and micro adjustment points. 1) Rotate the black adjustment knob counterclockwise to have it at its lowest strength. 2) Rotate the silver disc until the handles fit your hands. 3) Squeeze. Want more pressure on the handles? 4) Squeeze light on the handles, keep holding it, and turn the black knob clockwise to increase the Macro strength. 5) Readjust the silver disc to get the handle width to fit your hand. 6) Repeat until satisfied. 7) At some point, you can't handle the pressure from turning the black knob clockwise anymore but you don't want to give up the black knob's position. Simply adjust the silver disc so that the handles are closer, thus micro adjusting the strength down a bit.

The GD Grip Ultra 70 stands out for its customizable approach to grip strengthening. The innovative design patented in 2005 (US Patent 6881177) introduced an adjustment mechanism that caters to different strength levels and hand sizes, making it versatile for users ranging from professional athletes to those new to grip training. Adjustability is a highlight; it provides resistance levels between 44 and 154 lbs and adjusts the handle width from 45 to 85 mm. This allows for a tailored grip-strengthening session, fostering even muscle development from wrist to elbow—a plus for those serious about their training regimen. Another strong point is its durability. Constructed with steel and tough industrial plastic, the handgrip promises longevity and resilience against the wear and tear of regular use. This robust build quality echoes the commitment to a product that can withstand rigorous and repeated usage. However, I found the adjustment system frustrating, and it could have been more intuitive. There are no clear instructions on the packaging, so I had to rely on the instructions provided in the Amazon listing. Once you get the hang of it and fiddle with it for a while, you'll eventually find the right setting for your hand size and strength. The GD Grip Ultra 70 brings innovation to hand strengtheners, resulting from thoughtful engineering that presents a noticeable leap from the basic models.

Muy bufn producto y resistente tiene varios pesos para ir de manera progresiva pero no tiene una manera fácil de ver en qué peso estás y en lo particular el agarre no es muy bueno Aún así si buscas mejorar tu agarre si lo recomiendo por calidad precio.

Im Laufe der Jahre habe ich verschiedene Handgriff-Stärker getestet – einige aus billigem Plastik, andere mit vernünftigem Plastik und angenehmer Beschichtung – aber sie hatten alle dasselbe Manko: Die Metalfeder brach irgendwann, meist innerhalb von ein paar Monaten (bei mir waren es 3-4 Monate). Frustriert von diesen Ergebnissen suchte ich nach etwas anderem und stieß auf den GD PRO-70 Handgriff-Stärker. Was mir auffiel, war sein Design; anstelle der typischen Metalfeder verfügt er über einen anderen Mechanismus, der zuverlässiger zu sein schien. Also entschied ich mich, es auszuprobieren. • Dieser Handgriff-Stärker zeichnet sich durch seine robuste Bauweise aus und vermittelt sofort ein Gefühl von Haltbarkeit. Der Federmechanismus ist durchdacht gestaltet und bietet gleichmäßigen Widerstand ohne die üblichen Abnutzungsprobleme – ganz anders als bei den vorherigen Modellen. • Mit einstellbarem Widerstand von 25 bis 70 kg (55~154 lbs) ist dieser Handgriff-Stärker für verschiedene Stärkenlevels geeignet. Ich schätze es, den Widerstand leicht anpassen zu können, während meine Griffkraft sich verbessert, was mein Training effektiver und individueller gemacht hat. 👉 Gekauft am 19. Oktober 2022 – hat es sich durchweg gut bewährt, ohne Probleme wie gebrochene Federn, Risse im Plastik oder andere Mängel. ✅ Vorteile: 🟢 Robuste und langlebige Bauweise 🟢 Zuverlässiger Federmechanismus 🟢 Einfach einstellbarer Widerstand ❌ Nachteile: 🔴 Nichts, was mir einfällt Zusammenfassend lässt sich sagen, dass der GD PRO-70 durchweg solide Leistung bietet. Sein Design und seine Bauweise sorgen für eine problemfreie Nutzung, wobei die effektive Widerstandseinstellung das Krafttraining verbessert.

Very good product

Llevo un tiempo usándolo y llegó a la conclusión de que es tremendamente bueno es silencioso a más no poder buen agarre se cambia de posición con la rueda que tiene en el frontal y el muelle de resistencia te pone en tu sitio real no como otros que he usado que ya sea con un muellecillo y otros que no tienen tensión y al poco rato hacen ruidos y se atascan este es solido y silencioso
