GD GRIP PRO

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.

I really like this grip exerciser. I also have the GD Iron EXT 90 from this company, which is a work of art and will last for perhaps a thousand years. This one is not at the same level (there is some lateral give on the moving handle and some parts are plastic). That said I do expect this will provide years of use. This trainer is a little more difficult than the EXT90 to adjust the tension as you need to move two knobs and there does not appear to be a clear way of knowing the exact resistance to which you have set it. That said, the grip action on this is so much more pleasant because of the nearly parallel grip. The most important part, is that while I may admire the EXT90 (which is worth having), this grip trainer is the one I reach for and use far more frequently. Definitely worth getting.

Loving the build quality and overall feel, but I had to put four stars due to one flaw - front grip is too narrow and slippery to my taste. I glued piece of handlebar grip tape, 3 mm thickness, and it became so much better of a product. I wonder why GD doesn’t do it from the factory with some molded silicone.

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.

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.

My legs have gotten ahead of my grip strength. I can barely hold onto 300+ lbs when dead lifting. So I needed to increase my grip strength. I looked at those old school ones you see in movies where the head exec is squeezing one while yelling on the phone and chewing gum. But then I realized, once my strength improved, I would have to buy a new one. That's when I started to look for an adjustable grip trainer and landed on this one. It has been exactly what I needed. I sit at my desk reading e-mails or watching videos, I try to get each arm to 100 reps as fast as possible. Once it becomes easy, I adjust the tension by spinning the cap on the front. This thing has insane tension, it's no joke. I can't even come close to the max weight at this time. The other cool feature is the grip adjustment. As your increase the tension, it moves the grip around, so you spin the metal wheel and adjust the grip to exactly where you need it. It's a very well thought out design. It's a very sturdy build, and I have a feeling this is going to be on my desk for years. I am hoping one day to get to the max level for 10 reps in a row with each arm. p.s. As an added bonus, this increases my handshake game in the business world. People have noticed.

Just what I need at 82. Fortunately the lightest resistance is 44 lbs which I could do for repetitions with some effort. But my strength is coming back fast. And if 44 lbs is too much for some folks then use your other hand to give a little helping hand until your hand strength improves. It did take me a little while to figure out setting up the grip width and tension setting. It helps to read the directions.

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.

Extremely good quality, adjustable strength, made in South Korea.

Het is niet goedkoop maar wel top kwaliteit

Ergonomically far superior to the common, generic design offered by most other manufacturers. Easier, more consistent, comfortable and sustainable grip plus far easier to position correctly in your hand. A little more expensive yes, but it's definitely worth the few extra quid! Definitely recommend.

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
