Grip Strength Trainer, Hand Grip Strengthener with Adjustable Resistance 11-220Lbs(5-100KG), Automatic Counter, Ergonomic Design, Forearm Strengthener for Musicians Athletes and Injury Recovery

This grip strength machine is very good, first, the strength regulator, the range of grip strength can be set between 5-100 kg, suitable for different hand strength and different grip strength stage use. Secondly, it comes with an automatic counter with a counting range of 0-99, which is very convenient, and the count can also be manually cleared. Highly recommend this product!

This thing was built for Hercules lol on lowest setting it is tuff. I’m no slouch when it comes to strength as I’ve worked out half my life and this thing is a doosey. Gave it to a friend of mine who’s a professional arm wrestler and he even said it’s tuff to use. Adjusted on low setting even. Seems built well.

Not 5 kg to 100 kg! That is a joke. At 5 kg minimum setting it is nearly impossible to compress the spring. I have other hand compression devices that are 100 pounds to 300 pounds. This device at 5 kg is stiffer than the 100 pound devices. It may be used with both hands as a chect compression device but certainly not a hand grip device!UPDATE - The company replaced free of charge my device with a new device which has a reduced diameter spring. The new device is much easier to use and has an adjustable range. It more accurately fits the description.

This gripper is probably one of the best I’ve tried in this price range, with some creative features that I’d love to see in more premium grippers. Although, there could be some minor improvements that could be made which would elevate this gripper to perfection.For context, I consider myself an intermediate lifter with some pretty decent pulling numbers. For example I can do 405lbs x 4 conventional with no straps at 200lbs bw, so I’ve always kinda assumed my grip was decent. Not insane by any means, but maybe above average by non athlete standards. Ive noticed that my forearms have not grown much despite my strapless pull movements going up over the years. So lately I’ve been trying to incorporate more forearm focused work to build more proportional arm development such as wrist curls and extensions. The idea of a gripper appealed to me as it allows me to get some forearm stimulation from home without going to the gym.I’ve tried several types of these grippers, the cheaper adjustable ones and the captain crush ones as well. This one specifically is probably my favorite for the cheaper adjustable, as it has some features no others have.Let’s start with the pros:1.) the knuckle duster handle design allows you to keep your fingers from slipping even when your hands start getting greasy or sweaty. Compared to the other plastic adjustable designs you see here, which just have a rubber forward curved handle, your hands don’t slip off and you can bring the movement to true failure. This is an awesome feature for me personally.2.) this gripper features a rep counter! This in my opinion is one of the GREATEST features of this gripper, as it has a lot more functions than you’d initially think. It functions via a small button on one of the handles that clicks when the other handle depresses it once squeezed. This increments a small counter on the side of the device each time it’s depressed, showing you the number of reps performed. This is extremely useful as I sometimes like to do extremely high volume 20-50 rep sets; you’ll be surprised how often you over or under count your reps in your head at these rep ranges, so the counter is quite handy to double check you’re hitting same reps each hand.Moreover, the clicking of the button gives you an audible feedback for when you’ve completed a rep. It holds you accountable, if you don’t hear the click, you didn’t complete the rep! Great for reinforcing proper use of the gripper.An unexpected use case for it I also found is for isometric training. I often like to set the weight quite high, squeeze all the way down till I hear the click of the button, then set a timer. Once I hear the button click back up, I know my grip is beginning to fail and I stop the timer. Often times with isometrics, you actually fail max effort squeeze long before you actually notice your grip failing, so the clicking of the button gives you audible feedback for when your squeeze starts to fail. The rep counter mechanism is truly a genius feature of this gripper with more applications than you’d initially think.3). The resistance on this thing is the heaviest I’ve ever tried on ANY adjustable gripper. I’ve had many of those plastic ones and also the non adjustable knurled metal ones (captains of crush style ones). I would say this is great compromise between the plastic adjustables and buying a whole set of the heavier metal ones. If you’re looking for a gripper you can casually squeeze away at while doing something else, this is not it. Even the lowest weight is quite punishing past 30 reps for me, and I would say I have somewhat above avg grip strength. Not for total beginners, I would say good for intermediates or advanced intermediates. I have seen those big metal ones with giant red springs, if you have freak grip strength those might have a heavier resistance, but those are far more expensive than this one.Now let’s get into the cons, because there ARE quite a few of them.1.) the resistance numbers they claim on here are totally under represented. It says 5kg-100kg, but on its minimum setting (advertised as 5kg or ~10lbs), it feels at least around 15-20lbs of resistance based on my intuition (which is about 7-9kg). Nearly twice the advertised resistance. God knows what the max setting actually is. All I can say in that regard is, can’t even budge the max setting with my dominant hand. And the spring is SO STIFF, to even get it to its max setting, I have to use pliers to twist the small smooth plastic adjustment knob to get it to its max setting. Less than ideal. I’m sure someone stronger than me would have no problems but this is the case for me. Given this fact, it’s hard to actually tell how much resistance you’re using. My workaround is, I start at the lowest setting and count the turns of the knob to get to a repeatable level of resistance. So for example, you can track your progress by tracking reps at 3 turns one day, then the next week if you can get those same reps at 4 turns you know you’re getting stronger.2.) although the rep counter mechanism is amazing in terms of what you can do with it, the mechanism itself it does feel quite cheap. Theres a knob at the bottom of the handle you have to push in and twist to reset the counter. When you do this, the gears sometimes click and crunch in a rather unpleasant sounding way, which leads me to believe it’s made from rather cheap materials. Also, if you squeeze explosively and smack the button with some velocity, the counter sometimes increments by 2. I don’t foresee this mechanism holding up to prolonged use unfortunately.In terms of cons for this gripper though that’s all the gripes I really have. For the price, I believe it’s a pretty decent product for what it is, with some good features. I picked mine up on sale for 15 dollars which I think is good value. At its typical 20 dollars though, I think it’s still ok value but just know that the rep counter mechanism may wear out with time.Beyond this product, I do want to add some closing notes for people who are shopping for grippers and interested in forearm training/grip training. If your goal is just to increase your grip strength alone, I think these grippers are quite a good option.But if your goal is to actually grow forearm muscle, be aware that grippers only train the forearm flexors (muscles on the inside of the forearm) and not the extensors. If you’re a complete beginner to grip/forearm training, a gripper will get you some gains. But for hypertrophy training, I would recommend also including wrist curls AND extensions to your routine. Even though you need weights or cables for these movements, they allow for a full loaded stretch of the forearm muscles which in my opinion leads to better hypertrophy stimulus. All grippers have a relatively limited range of motion, even less so if you have particularly large hands. The grippers are great for strength and convenience but if you really want to build big forearms, you should not rely on grippers alone if you are an atleast intermediate level lifter. Just my 2 cents.TL;DR: IMO best of the best when it comes to the “cheap adjustable grip trainers”. Has some unique features that allow for creative training styles. Provides some SURPRISINGLY high resistance. However, my fav feature (rep counter) feels cheap and i foresee it breaking with prolonged use. And the resistance numbers on the device are understated. Decent value for 20 dollars, but if you can pick it up on sale for 10-15 dollars I’d say absolute steal. Overall I recommend this gripper, but it will be a bit intense for newbies even on lowest setting.

Conceptually an adjustable gripper is a great idea. Owning a whole set is annoying, and you can get stuck in between different grippers in a set when trying to progressively overload.But there are a few serious problems with this item you should be aware of in deciding whether to purchase:1. The lowest setting is FAR above 5 kg / 11 lbs, as claimed in the item description. I would say its AT LEAST 45 kg / 100 lbs. That may not be a dealbreaker for most healthy adults, but if the gripper is for a child or someone rehabbing a hand injury, they might not be able to close it on even the lightest setting.2. There's really no way to even roughly measure what setting you have it on, which makes progressive overload quite difficult. To try and solve this, I marked the dial with a sticker and try to count how many twists I am on, but its clunky. Having some indicator what strength setting this is on would be WAY more useful than the built-in rep counter they included in the handle.3. The rep counter is kind of a neat idea, I guess, but is clunky to reset. I usually ignore it because its easier to just count the reps myself rather than reset it.I bought this item because I was having a tough time making the jump from a 150 lb gripper to a 200 lb gripper, and it did help me with that, so I guess it served its purpose. But make sure it will work for what you need it for.

Very well constructed and designed. I just started using it and my grip is notably stronger.

Feels like a quality unit. Fast Shipping

As a competitive arm wrestler, I've tried countless grip trainers claiming '5kg resistance' that felt like squeezing marshmallows. This product is the REAL DEAL – the 5kg base setting actually requires focused effort. The progressive resistance up to 100kg finally gives me measurable strength gains. Finally a tool that doesn't baby my training!
