Overview:

GD Iron Grip EXT 90 is elegant yet rugged, silent yet unrelenting, and rough yet ergonomic. Indeed, it has outperformed all my expectations.

The ultimate gripper is designed to have perfection, quality, and solidity & the only important thing is adjustable- Probably the only gripper you’ll ever need. Personally, this hand gripper is my favorite one as it provides the most features, like other hand exercise equipment would, and more.

With a single gripper like EXT 90, you’ll get 6 different grippers. Very nice to take into consideration all the factors of an effective workout. Warm up, working sets, challenge sets, cool down sets.

It is also equivalent to popular Captains of Crush grippers that are considered to be the gold standard in the market of hand grippers. EXT 90 has a more aggressively knurled gripping surface compared to CoC grippers. Do not let it slip from your hand for a better grip while you are working out conveniently & efficiently at the same time.

Superbly Engineered

Pros:

It’s Adjustable – Comes with 6 (six) different resistance levels- Undoubtedly the biggest advantage! Gone with the days of buying separate grippers; this one is your only choice unless you’re a grip training addict like me.
Durability – Superiorly built, sturdy, attractively designed, and relentlessly efficient – A pair of tongs you probably only buy once because it will last you for years.
Not Squeaky – It’s firm and silent, & its spring cannot squeak nor make strange sounds. No matter whether you prefer a quiet library or not, make sure you do not annoy others around.
Ergonomic – Properly constructed, fitted & comfortable, with the ability to train your hands for a crushing grip, while not injuring yourself.
Knurled – Up your gripper’s top-level look with knurls that also have an aggressive knurling on the palm side to keep your hand from slipping off handles.
Extensions are included – Extensions are being made for longer handles & they are meant to help you get a better grip in the event that you have bigger hands. or you may want to push yourself with some hard exercises.

Cons:

Involves investment – Certainly, this hand gripper is expensive. You should take your time, & think it through if you need one: Treat it as an investment. It is a 6-in-1 unit, thus pricey, but with all its worth it.
Handles don’t touch – Not really a con, but just putting it out here: Unlike most grippers, however, their handles are aligned in such a way that they won’t touch each other & grind completely. It does not have limitations for motion but has another feeling as its impact.
It can be hard for newbies – For those who are beginners, it could be a nutshell to break. The first difficulty level starts at 55 lbs / 25 kg.

Six Grippers in One

A useful and adjustable gripper that grants us the possibility of choosing twice the number of resistance level options for half the price we normally pay for regular grippers. This is just the math, the cost of materials for individual grippers, as well as other stuff.

So if your adjustable gripper fails, you will be robbed of all training options at once. Probably individual grippers wouldn’t collapse at once, so it’s a good idea to have a backup. On the other hand, it is so in theory. The great thing is that an adjustable gripper saves you a lot of headaches & is much cost cost-efficient.

The Iron Grip has the widest range – from 55 to 198 lbs (25 to 90kg), no matter if you are a beginner or an expert. Plenty of progression room. Owning the Iron Grip Adjustable Grip 90 EXT is like possessing six different hand grippers.

Excellent for Training Both Hands

Compared to regular classic spring grips, the EXT grip’s axis of the handle is not twisted.
It’s a peculiar innovation for the GD line of grippers.

So what does that mean for you? First & foremost, more convenience. Instead of getting specialized grippers for both hands, such as right-wing & left-wing spring grippers, you can use EXT grippers for both hands & they feel pretty much the same way. It has a more ergonomic design than most other grippers can offer you.
