Grip Strength

Posted by Mike Gittleson on Jan 4, 2014 6:11:00 PM

Strength of the grip and strength of the fingers are highly correlated. The contribution of the index finger is about 25% of the total force, the middle finger 35%, the ring finger 25% and 14% of the force is contributed by the pinky. Looking at these values you can see that the radial side or thumb side of your hand contributes about 60% of the hands gripping power and the ulnar side 40%.

Body size and finger length are moderately correlated with strength. Much of the closing power of the hands comes from the extrinsic muscles that make up the forearm, as fingers are moved by tendons which are pulled by these muscles.  It has been shown in studies that as little as a 2 cm change in circumference of the forearm can affect gripping power.

The absolute best way to increase overall hand strength is training, whereby the musculature is forcibly lengthened, commonly referred to as eccentric exercise or negative only training. Tyler Hobson the designer of Pendulum built the Pendulum Gripper not only to exercise by closing the hand, but developed a tool for lengthening contractions.

Using the foot pedal on the Pendulum Gripper to assist in negative only training

To maximize hand strength load the gripper with a weight that can be squeezed tight for a full second and then lowered slowly for an 8 count. Quickly the athlete uses their foot to close the gripper and once again hold the weight with no movement for a full second before lowering the weight in 8 seconds.  The hand  must be halfway open on the count of 4. Every inch of the exercise is important, being half way down in four seconds means that the athlete is 1/4 of the way down in 2 seconds and 1/8 of the way down in 1 second. 

Eccentric Grip

Each rep is counted from the squeezed position until the index finger becomes almost completely extended as shown

Perfect repetitions is what the coach and athlete are after, the exercise is completed when the lifter can no longer control the decent of the weight at an 8 second pace.  When 8 perfect reps are achieved in exactly 8 seconds, 2 1/2 lbs. can be added.

Grip Strength

The skeletal muscular system is involved in much more than locomotion; it is also a complex organ system.  Skeletal muscles are enmeshed in heat regulation, blood movement, balance, and the health of the entire anatomical system.

An indicator of overall muscle strength and how much muscle mass an individual has acquired historically has been assessed through grip strength.  Scientists, physical therapists and physicians have used hand-held dynamometers to measures overall muscle power fairly accurately.  Having more muscle in the upper body means there is probably more in your lower body as well.  If muscle strength is abnormally low it can be predicted that an individual is further down the road to frailty later in life.  The American Medical Association indicates that men with good hand grip strength in "midlife"  report much less disability related to muscle strength twenty years later. 

Measuring the gripping strength of the hands is also an indicator of nutritional status, bone mineral content, and functional integrity of the upper extremity.  Low handgrip strength has been consistently linked to health complications, symptoms of depression, obesity, cervical spinal cord lesions, and even  premature mortality.  Getting Strong and staying strong throughout life has tremendous benefits.

Sledge Hammer Finger Walk

Ab and Adduction of the fingers is done by 'finger walking'.  When an athlete Gets the finger ab and adductors Strong they are able to hold on to objects or pull objects towards themselves without their grip slipping.  Having ab and adduction strength is as important as having the ability to powerfuly close the hand.

With the emerging world of robotics and the mechanical design issues of grasping objects, hand kinematics has become a major field of study.  Scientist spend countless hours on discerning how the placement of individual fingers on items is affected by the end-goal action of  lifting, raising, throwing, catching and moving.   Hand placement on the object to be grasped is affected by the nature of the upcoming task to be performed following contact.

Depending on the accuracy requirements and what the individual intends to do with an item affects how the hand is shaped during the reaching movement.  How people grasp objects can give insight about the movement that is being planned afterward.

The thumb and index finger have a stronger force production capability compared to the other digits.  For maximum grip strength people assume different upper-limb postures.  It is well known that grip strength can be affected by positions of the upper extremity and coaches use posture to augment particular exercises.

Wrist Roller There is a standard protocol for measuring grip strength recommended by the American Society of Hand Therapists.  The subject is seated with the shoulder adducted and neutrally rotated, the elbow flexed at 90 and the forearm and wrist in neutral position. The point is, as a coach using a standard protocol to measure grip strength is necessary  in order to fairly compare athletes.  

Pendulum Gripper Test

The Pendulum Gripper is a Great Testing Tool for Grip Strength

There are basic anatomical classifications of the types of ways our hands and fingers interact with objects - power grip, pinch grip, precision grip, hook grip, ball grip, finger abduction and adduction - are standards of interactions that must be addressed when designing exercise protocols.  These grip variation have to do with the number of digits, their placement and the amount of palmer surface used when a person interacts with a gripping device.  These variations of hand grips and grasping techniques determine how much of our musculature and how much of the extremities can be used to add or reduce gripping power.

The Pendulum Grip Cart was designed to carry all the tools necessary to train each anatomical variation.  Each grip apparatus on the cart has an associated rule for lifting it. Having athletes interact with all the devices throughout their careers insures that they will have an opportunity to maximally strengthen all the musculature of the fingers, forearms and hands to Get Strong.

Training with thick bars and with handles that have wide grips helps to develop hand strength. Changing the grip width for select athletes with large hands actually makes the exercise feel natural as the majority of handles on exercise bars and machines are made for the normal population.  Ask Rogers Athletic about adding thick handles to your Pendulum 3 Way Row.

Strong Hands

Posted by Mike Gittleson on Aug 20, 2012 9:23:00 PM

Strong Hands 

The British Strongman and performer Thomas Inch was an early-twentieth-century strongman famous for his grip.  He, for decades was proclaimed 'Britain's Strongest Man'. Inch was known for lifting what is today called the 'Thomas Inch Dumbbell', a cast iron thick handled bell that weighs a hundred and seventy two pounds.

It was said no man in his era could even clear it off the floor.  Inch offered a prize of more than twenty thousand dollars in today's currency to anyone that could lift the fabled dumbbell with one hand.  Todays strongmen still proclaim success when they match the 100 year old feat of Thomas Inch.


Mike Gittleson was the Director of Strength & Conditioning at the University of Michigan for 30 years and was a part of 15 Football Championships in that time.  He explains, what can happen when you emphasize training the grip. 

Kim Wood is my friend and was the Head Strength Coach of the Cincinnati Bengals.  He owns the original Thomas Inch dumbbell, which he purchased and had shipped to the USA.  Kim sent me a replica as a gift.  I had a stand constructed and placed it in the football weight room.  If anyone could pick up the bell with one hand and stand straight I placed their name on a plaque and dated it.



I figured and rightfully so, that today's football players were as strong as many amateur and professional strongmen from any decade and with our hand strengthening program athletes would be able to accomplish picking up the Inch dumbbell over time.

The dumbbell sat on it's mount and became a silent goal in the weight room.  Year after year athletes' names began to grace the dumbbell stand.  One of our centers, Rod Payne thought it was too easy to pick up and believed athletes should clean it or press it to be recognized.  Lifting the Inch dumbbell is far from easy yet once you get your hands strong maybe for some it is.

I used many exercise devices for augmenting hand and finger strength.  Yet my favorite tool for developing hand strength was the Pendulum Gripper.  I had four lined up in the grip area and they were used every hand training session not only to strengthen, but to measure and record progress.  A great tool for Getting Strong.
