Product Description

Amazon.com Product Description

Isolating each finger so it can be exercised individually, the patented Gripmaster strengthens hands, wrist, and forearm with spring-loaded piston technology while ensuring the palm doesn't slip from a molded grip. This model offers heavy tension (nine pounds per finger) and is recommended for men for extra-strong hands. Sturdy and highly durable, the Gripmaster easily fits in pocket or purse, enabling hand exercise anytime, anywhere.

A few daily workouts with the Gripmaster Pro and you'll enjoy better control of a baseball/softball bat, tennis racquet, or golf club, with each finger working in seamless unity with the others. You'll also find a ton of other uses for the Gripmaster Pro, including playing guitar or violin, rock climbing, bowling, target shooting, martial arts, yoga, or even relieving stress while clicking a mouse or gaming for hours on end.

Exercising with the Gripmaster is the most efficient and effective way to maintain the health and conditioning of the hand. It's the ideal way to maintain the suppleness and flexibility of the hand to prevent injury. Each finger of the hand is powered by a completely separate system of muscles and tendons located in the hand, wrist, and forearm. The ability to control the ball or control the bat, racquet, or club all starts with the hands. Your hand is really five separate systems which work in seamless unity. The only way to develop superior strength, endurance, and coordination in your hands is to challenge and develop each finger individually. Once you exercise with Gripmaster you'll notice a difference almost immediately.

Product Description

The patented Gripmaster is the only hand exerciser in the world that exercises each finger individually for optimum conditioning of the hand, wrist and forearm.

5.0 out of 5 stars Improved Guitar Playing In 2 Weeks, June 8, 2007

By 

Rahman (CA, USA) - See all my reviews

This review is from: Gripmaster Hand Exerciser Black, Heavy Tension (9-Pounds per Finger) (Sports)

With a weight-training background I already have a number of products focusing upon forearm and grip strength. This by appearance and description seemed to fit a very specific purpose, what could be called finger-tip strength, so I went ahead and gave it a try.

Receiving it, the high-quality construction was immediately noticeable. Beginning with the highest tension [black] gripper, I began use intermittently, whenever web pages loaded in slowly, between television commercials, and so on.

I had no idea why during my twice-a-month hobbyist guitar playing, I was able to play with a marked increase in speed and accuracy. The fingers occasionally seemed to be pulled onto the fretboard like magnets. Thinking about it for a few minutes, I realized this device was the only significant change I had made over that time. Typically I had to warm-up for at least 30 to 45 minutes before my hands correctly played quicker fingering patterns. There was no lag time this time.

For the price and diminutive size of this device, it is surprising how effective it is at its focused purpose. I also noticed that, while my typing has not gotten any faster, I can type somewhat longer without becoming self-aware of fatigue.

--------

There are several reviews for this gripping device that claim insufficient resistance, even with the highest tension [black] version. This may be due to a misconception of the purpose and usage of this particular device. It is what could be thought of as a finger-grip strengthener, as opposed to those devices which develop palm grip-strength, which are far more common and found at any sporting goods store.

The tell-tale sign of improper use, is through where you position your grip when performing the exercises. If you find yourself grasping at mid-finger level, between the first and second knuckles, and squeezing all of the fingers together at the same time, pumping over and over again, you are using this improperly. You are to place the very tips of the fingers, before the first knuckles, on the finger-rests, and proceed to provide force with individual fingers, alternating with other patterns such as all four-fingers simultaneously as well, but always with this positioning. If you try using this device as a mid-finger, mid-grip strengthener (with the device ending up resting against the palm of the hand), you are using it incorrectly.

For a mid-grip strengthener, Captains Of Crush is very highly recommended. These provide massive amounts of resistance, and are for the more typical mid-grip strengthening exercises. Even the trainer, Captains of Crush Trainer Gripper, will at the beginning be highly difficult for most athletes. The efforts are well worth it, however, these are extremely high-quality devices. There is actually official certification for doing their highest level grip one single time, for one single repetition (the two ends touching). Through these you can perform the more typical palm-strength exercises.

Both the C.O.C. type of palm-level strengthener, and this Gripmaster fingertip-level type of strengthener, are needed for more complete and balanced grip strength. Doing exercises focusing on the forearms directly can also be very important. Any grip exercises strengthen the forearms as well, but only indirectly. It depends on how important overall lower-arm strength is to you. In any case, the Gripmaster is for working the most distal part of the grip, that is the tips of the fingers. Working it any other way, is not using the device for what it was designed for.

5.0 out of 5 stars Heavy Tension (Black) is better for men, February 25, 2006

I bought both the Medium and Heavy tension Gripmasters. The Medium (red) one is not much of a challenge for me. I'm a man of average build, and I actually bought these because I was starting weight training at the gym and I wanted more grip strength for my hands and stronger forearms.

I'd say if you are looking for individual finger strength, such as for playing an instrument, then the red Gripmaster might be enough resistance. But I use the black one much more for whole hand strength.

The product comes with a guide containing instructions on a variety of exercises. I would also recommend visiting Gripmaster's website, as they have a more complete list of exercises, and recommendations for different sports.

5.0 out of 5 stars If you Need Finger Strength, Control, Endurance and Coordination, you are in the Right Place, July 31, 2006

By

This review is from: Gripmaster Hand Exerciser Black, Heavy Tension (9-Pounds per Finger) (Sports)

Let me start saying that this is a wonderful product. Small, light, and well constructed (they feel like they will last forever). You can carry them with you, allowing to workout your fingers at the office, at home or wherever you find suitable. I bought the four different color-coded gripmasters: Black/heavy, Red/medium, Blue/light, and Yellow/extra light. I only found the resistance of the red and black ones useful for me, but my wife loves the blue and yellow ones. It was a great buy because of their high quality and affordable price.

The product comes with a foldable instruction booklet where you find details for six different exercises:
- Trigger pinch. This one simulates the movement of squeezing a trigger, and it isolates the index finger for enhanced strength and coordination.
- Gross grasp. This one strengthens fingers, thumb, wrist and forearm for a firm grip.
- Hook position. This one strengthens longer muscles in forearm and wrist while stretching smaller muscles in hand for greater motion and endurance.
- Tip to tip pinch. This exercise strengthens specific fingers, thumb, smaller hand muscles and forearm for greater control and endurance.
- Wrist flexion. It strengthens wrist and forearm muscles.
- Key pinch. Strengthens thumb and index finger for greater stability and coordination.

At the gripmaster website you can find more exercises for different activities and sports.

If you are looking to crush hands when handshaking this is not the product for you, but if you need finger strength, control, endurance and coordination you are in the right place.
