GDGrip 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.

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.
