Excellent Grip Feeling! 4 link structure!
Constructed with a four-link structure it can operate in parallel with the handles. This enables a natural operation, coinciding with the movement
direction of the fingers, with fixed pressure corresponding to each fingers.
Similar to Hand Dynamometer
The handles work in parallel like a hand dynamoneter, so the resistance is applied evenly to all fingers.
Adjustable resistance and width of handles!
The GD Grip Ultra 70 is an adjustable hand gripper developed for professional athletes and everyone else. The resistance can be adjusted between 20 and 70kg (44 to 154 pounds). Its width of handles is adjustable from 1.8 inch to 3.3 inch. These combinations enable the user to make a choice from 17 different resistances.
How to adjust resistance and width of handle?
Grab the hand grip slightly
First, grab the handles of GD GRIP ULTRA slightly until the resistance adjusting nut going forward.
Turn the resistance adjusting nut
While holding the handle, turn the resistance adjusting nut downwards. (Turning it more, it will getting harder)
If the resistance is too hard for you, grab the handles strongly and turn the resistance adjusting nut to the opposite direction.
Turn the width adjusting nut
Open the handle and turn the adjusting nut to fit your hands size.

I have squeezed this trainer thousands of times at this point, and have really grown to appreciate it's quality and utility. The resistance is adjustable. The grip is comfortable. The ability to adjust for hand size is also really nice.After the first few hundred squeezes, some white lubricant gel did appear around some of the mechanics. I just wiped it off and have had no more occurances of that. I think this is a great trainer.

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.

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 einfälltZusammenfassend 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.
