Professional Hand Grip Strengthener 200lbs-1200lbs, No Slip Metal Adjustable Heavy-Duty Finger Stretcher with Carry Bag,Weighted Great Wrist & Forearm Exercise, Arm Strength Builder, for Home Office &

Wow exceptional strength trainer. It definitely seems to be a pro product. I first seen this while doing physical therapy. I decided to buy it since the other hand grip trainers were to easy. The springs would end up snapping to easily. This is awesome. It comes with carrying pouch and 6 springs. I haven’t gotten past 2 springs depending on placement. It has notches where you can adjust the springs placement from easy to hard. Not sure how many pounds of pressure it takes but I believe I seen somewhere that it goes up to 500lbs. I’m no where near that. I would be nice to know where to place springs for what poundage but it doesn’t show you. Great product good luck maxing it out.

Let me offer the following explanations. I have strong hands. I've always had strong hands. Among other things I worked as a carpenter and cabinet maker for many years. I'm now almost 74 and at the age of 65 was recruited into an international medical study on the use of aspirin. Among the attributes periodically monitored was hand strength. My local, Detroit peer group at Wayne State University Medical Center has been about 500 seniors. I was told that my hand strength for this group was number one. I didn't get this device for therapeutic reasons. I don't have arthritis or carpal tunnel, etc. I have a Glock 42. The 42 is a 380 ACP weapon and the trick to using it properly is holding it firmly so that the blast from the explosion will power not only the bullet but also power the slide back to eject the casing and load a new round from the magazine. This is a semi-automatic. If you don't hold the gun firmly the gun will jam. I was shot in an attempted holdup in Los Angeles as a young man. Unfortunately I brought my fists to an unexpected gun fight and was the loser. Never again. The Glock 42 is the ideal conceal carry. It is light and goes almost unnoticed as opposed to, for example a Glock 23 or 27. Those are 40 S&W and (by comparison to the 42) feel like you've got a brick in your pocket. So I got the hand strengthener to both strengthen and train my hand grip. This is a self-defense project. I swim and cycle daily and have a weight room. However, until now nothing specifically for improving my grip strength. This device has six springs, is all high quality steel, and truth be told, it's extremely easy to scale the increase in tension as your grip strength improves. You just move the springs, notch-by-notch, away from the pivot point. It's obvious and easy. The physical dimension of the device also mean that the angle between the gripping surface is less acute and the grip movement seems more proportionate and natural. You contract and release by a slow 1-2-3 count in each direction. I was somewhat surprised that this was the only device with such a design but there you go. The other plastic things seem like toys by comparison. If you're going to spend the time to achieve a serious goal - buy the good stuff. I don't think that a human Godzilla could exhaust the potential max resistance on this thing and its quality construction mean that this is a forever device. If you are serious about improving grip and hand strength I haven't seen anything to beat it.

I prefer this over the more traditional grippers. It feels less technique demanding and more centered on raw strength. It feels like you are getting stronger and not just better at closing a specific tool.The massive range that you get for the price is totally unbeaten. You can go really light, so I could see this being ideal for people in physical therapy. On the opposite end, you can load this thing up to the point where I am doubtful if there are many people alive that can close it.The only downside this one has over your more traditional grippers is it's more bulky. So you can't really put this one in your back pocket.

Pros: this thing delivers with weight and resistance, strong springs, solid-quality materials, nicely spaced handle, easy to grip, easy to useCons: VERY difficult to move springs, handle is somewhat loose and wobbly, no instructions

The only flaw is that they don’t provide you with any chart showing you the tension settings. However, progressive overloads don’t care. All progressive overloads care about is that you are increasing the tension, and this does that in spades. In other words, if you want to strengthen your forearms, then this is the best, well built, solid, cost effective device I have found, and there is simply no way that you will ever max out this device. In fact, I will tip my hat to you if you can use three springs at max tension, leaving 2 springs as spares.

This thing is fantastic, buy this monster!It’s a machine of range and design.The range of weight you can achieve.The range of motion, and dynamics of that motion.Unparalleled.It’s perfect no matter your goals, makes me wish I had a 6th star to give this thing!

This gripper is awesome.So my grip strength on a dynamometer is 100 pounds. On the setting in the picture I can close it 3 times. My hand size is 7-7.5 inches from wrist to tip of middle finger.I currently have one of the cheap grippers from amazon with the curved handles which go from 10-60kg. Although cheap they are fairly good. I can close the max of those about 4-5 times. The minimum on this gripper is about half the strength of the minimum of the 10-60kg one.It has a good feel. It has a slight increase in resistance as you close it. The 10-60kg one almost feels like it has the same resistance all the way through. I feel like using this gripper way more than the 10-60kg one, it just feels good. It could be because the handle are more parallel, I'm not sure, I just know it feels good to use. It also has a nice long range of motion.There is no way you will be outgrowing this gripper no matter how strong you get with the additional 5 springs.Pros: Capacity beyond what your strength will ever get to. Very fine gradients to increase the resistance. Nice long range of motion and feel of resistance throughout. Handle close to parallel. Due to design I can't see this breaking, if it does, easy to fix yourself.Cons: Size is basically the only con. You aren't going to be carrying this around with you when you drive to do some grips when running errands.

Well made.
