Captains of Crush Hand Gripper Left-Turn – Review

Overview, Details & Everything Relevant You Need To Know

[/nx_note][/nx_animate]

[nx_heading style=”underlined” heading_tag=”h2″ size=”21″ align=”center”]What is Captains of Crush Left-Turn?[/nx_heading]

Overview:

CoC Left-Turn is a brand-new concept – It is the opposite of Captains of Crush hand gripper, featuring mirror image grippers that train your left hand.

It’s about spring positioning: For example, if you flip the right-hand gripper over to your left hand, you will notice the elliptical rotation of the hand gripper axis. While some people find grasping with a gripper awkward or uncomfortable, others may describe it as being more difficult to close a hand.

To make things even for your left hand & train it the same way you’re training your right hand, IronMind decided to build an entirely new gripper that looks like & technically is the Captains of Crush gripper, with one difference: It has used the left of the spring, this gear suits training the left hand well. Left Turn is the opposite of Captains of Crush.

In case you’re a weightlifter, rock climber, wrestler, or motocross driver, a strong grip is typically a must-have to be a top-notch performer.

Unlike regular plastic grippers, CoC Left-Turn has high reusability. It has aircraft-grade billet aluminum & alloy steel construction, making it outperform others in competition. Established in 1988, IronMind is a pioneer in the field.

Besides a 1-year guarantee on their world-famous spring grippers, the manufacturer also ensures replacement in case the gripper gets damaged.

Knurled Lefty Gripper

Pros:

Lefty Gripper – It is one of the very few grippers that utilizes the left-handed spring specially designed for the leveling of your left hand, as you do with your right hand.
High-Level Equipment – Approved for low-volume, high-intensity training. Custom-machined device made out of aircraft-grade aluminum alloy.
4 Different Resistances – You can purchase different stipple grippers that can be used as alternatives to train both hands at the same time, as the regular Captain of Crush one. Available resistance range of 100 lbs to 280 lbs for an absolute beginner to an expert workout (100-280 lbs).
Absolute Durability – That goes for all CoC grippers; they are all made of metal parts to aid in strength. – Therefore, you will not find any parts that are made of plastic as they are not as strong, partly degrade, or can easily break over time.
Aggressive Thickened Handles are one of the crucial ways to achieve not only stronger but also tougher skin on your palms. The palms of your hands sometimes can have a feeling of being chopped apart or torn by the extremely strong CoC gripper knurling in order to make them much stronger overall.
Portable – How easy is that? Just pocket one or leave it in an offset desk drawer. By the time you leave home, you can also add one to the backpack you will carry for your training class. This is a small tool. Therefore, it will always have one or the other with the grip work.
Easily Maintainable – For metal grippers, we often have to consider corrosion in humid climates. To prevent the spring from rusting, you should frequently wipe it with only a drop of oil that will not just make it move smoothly and stop it from squeaking, but also reduce the chances of its breaking. Knurled handles, too, should be cleaned using stiff nylon-bristle brushes
1-Year Warranty – In the case that your grippers fail within the first year after the point of purchase when used appropriately, you can replace them for free.

Cons:

The One Hand Model – The learning model is configured to work with your left hand at the outset. And while it is indeed a good practice, it is still quite effective for training both hands, with a slightly different feeling when doing it with your right hand using your left. Unless it’s a tiny detail that no one can tell, I advise you to opt for a standard Captains of Crush trainer in addition to your lefty gripper if you want to train your right hand to be the strongest and the most precise.
A Single Resistance at a Grip – In contrast, the CoC is a static resistance only at the gripper limit of the training tool. To get remarkable results, you probably have to take a step further by purchasing grippers with different resistances, and this may require some more coins from your side.

Fastest Way to Build Crushing Grip

[nx_list icon=”icon: arrow-right” icon_color=”#229d3d”]

Improve Your Finger Tendon Strength – This is one of the most important aspects of your hand health & strength: The capability of performing your regular activities and exercises is ensured by the fact that you can act with your hands. This gripper improves the condition of the tendons, which can then be used for harder exercises.
Generate Maximum Crush Grip Force – Hand movements happen in four categories, & crushing is one of them. If you are looking for something to grab, you use a crush grip to hold it. The hand gripper is the #1 most effective device for jacking up your hand-crushing strength in no time.
Keep up the static support grip – Gripper is a tool where you squeeze the handles together, hold them closed for as long as possible, & then remove your hands. This is more of a top-priority exercise for you if your main load is a heavy barbell, for example, like this, you can work with more weight and a longer period.
Do not kill your palms off – If you’ve never trained on grippers or parallel grips before, watch out for the knurling on this one, which can beat your hands really quickly. As a result, this is a good thing – this is how your hands become stronger. The trick here is NOT to use your gloves but to throw them out of the window instead. Only use your palms to train them to be stronger.
For this, you will need to build a well-prepared grip – one of the most important things to play the sport in a proper way is to have a better grip. Having a total more stable, powerful, and less fatigued grip helps you to carry out your workout routines correctly and also have a bigger chance of winning over the competitors.
Protect Hands from Injuries – Extra pounds of muscle will be great. This removes a lot of stress from our bones and joints. Improving functional strength together with overall muscle mass brings your healthy hands to life & decreases the risk of possible injury. It doesn’t matter what sport you are playing; your number one goal should be to avoid injury.
Possibility to Obtain a Certificate – Grip Training with the higher CoC hand grippers that eventually close it will not only give you the chance to become famous but also allow you to be recognized as the strongest man in the grip world. Closing CoC 3, 3,5, or 4 grippers is considered a great feat of strength – You will get a diploma with your name written down in IronMind’s official catalog.

Any Athlete – Men & Women, Older & Younger

Hand grippers will work for both novice and advanced trainees to get their grip stronger or even stronger than they already have.

Whether you are a teenager or a senior, male or female, and a casual recreational athlete or a hardcore, training grip allows you to have functional power, which you use and most likely will use every single day. In most sports, the very first thing that your hands make contact with is an object. Whether you hold a basketball, a baseball bat, a golf club, or a weightlifting barbell, it doesn’t matter.

The more functional strength you gain in your hands, the higher the performance in your specific sport is also likely to be.

Avoid Fitness Gloves

Why should you be careful not to overuse fitness gloves? A lot of people depend entirely on gloves when they hit the gym, and therefore, they often have extra soft palms. Gloves are like “strangers” to your hands (between your palms & the bar you are lifting) that take the real strength of your palms away.

That’s the case. As soon as you take off your fitness gloves and touch the first barbell or dumbbell, you will injure your hands badly. Your hands start hurting, and in the end, you probably have blisters.

Therefore, what is your solution to the problem? And no, you don’t put gloves on. Captains of Crush grippers have knurled handles for roughing the palms of your hands purposefully. Continue to practice; your strength and accuracy will improve. Slowly but surely over weeks and months, as you continue to grip, the skin in your palms will become tougher. It is one of the main components of being able to do more intense work without any equipment.

Unless your hands are injured, OR you’ve already used your hands to extreme limits, you DON’T have any more excuses or likely any practical reasons for using fitness gloves – you need to put them away & work with bare hands for functional strength.
