Gazing at the "Absolute Control" skill effect introduction displayed on the panel, a look of understanding flashed in Fang Cheng’s eyes.
From the perspective of sports dynamics, the training of pull-ups is one of the ultimate exercises for honing grip strength.
It requires the trainee to firmly grasp the support with their fingers, relying on the concentric and eccentric contraction forces of the forearm muscles to counteract their own weight.
This process deeply stimulates the flexor digitorum superficialis, flexor digitorum profundus, and even the palmaris longus, the core muscle groups in the hand.
During the dynamic phase of pull-up practice, that is, when pulling the body upward, the fingers and palms must actively tighten, generating explosive grip strength to fight gravity.
In the static hanging phase, the hand must continuously perform isotric contraction to maintain body stability, which trains the endurance of grip strength.
Ordinary people can’t do many pull-ups, not only due to weak back muscles, excessive weight, or incorrect exertion techniques, but also directly related to insufficient endurance and explosiveness in the forearm muscles.
Usually, the hands run out of strength first, while the back muscles have not yet reached their limit.
Therefore, many top rock climbers possess fingers as strong as iron clamps.
They regard practicing pull-ups and its various variations as a core thod for honing grip strength, its importance even surpassing back training.
After long-term training, one can significantly enhance the hand’s gripping strength, reaching several tis that of ordinary people.
Now, after mastering the pull-up skill to the Grandmaster Level, it’s only reasonable to derive such a domineering effect.
With his mind whirling, Fang Cheng was eager to experience it firsthand.
He quickly walked to the wall and picked up a brand new 20kg dumbbell from the corner.
His five fingers grasped and wrapped around the cold knurled handle of the dumbbell slowly.
The rough tallic sensation vividly transmitted through the skin of his palm.
Fang Cheng didn’t deliberately exert force, just naturally stood and clasped it tightly like lifting any heavy object.
The next second, Fang Cheng’s gaze sharpened, and his waist and back trembled.
Strength instantly conducted from the core along the spine to the shoulders and back, and then pumped into the arms like a high-pressure pump.
Then, the forearm muscles suddenly swelled, with the knotted muscle lines like tangled steel cables.
All the power converged at the fingertips of the five fingers in a split second!
"Creak—shriek—"
A chilling tallic twist and wail suddenly resounded in the quiet room.
That feeling was less like tal being compressed and more like a piece of wet wood being forcibly squeezed dry.
Fang Cheng exhaled a sigh and slowly released his fingers, squinting intently at the sight.
There, on the hard cast iron handle of the dumbbell, five faint white finger imprints were faintly visible, as if branded upon it.
Emitting the unique pale luster of a tal’s molecular structure being destroyed by violent bending.
By eye estimate, the depth of the dents was at least half a milliter!
"Hiss... this is a bit outrageous."
Fang Cheng muttered to himself.
Such solid cast iron seed to him as if it were a toy that could be kneaded at will.
It’s worth noting that for human fingers to perform delicate operations, their evolution favors dexterity over sheer strength.
The muscle groups involved in gripping power are relatively weak components of body muscles.
Generally, an adult’s limit grip strength is only about one-fifth of the impact force generated by a full-force punch.
With Fang Cheng’s near 50-point strength attribute, even without using the "Kirin Arm" skill effect, a simple straight punch can dent an iron plate with a clear fist mark.
But that’s a result of body strength transmitted through kinetic energy concentrated at the knuckles.
Trying to imprint similar marks on cast iron of equivalent hardness with the structurally weaker and more isolated exertion muscle groups in five fingers is exponentially more difficult.
To achieve such an effect relying solely on a near 50-point basic strength attribute is nothing short of daydreaming.
However, now, the skill effect of "Absolute Control" has rudely amplified the instantaneous burst grip strength by 1.5 tis.
This barely allowed Fang Cheng to touch the threshold of martial arts novels, where fingertips chill and can break tal and iron.
"It seems that as the strength attribute steadily increases, purely using five fingers to crush steel bars and iron rods is not unattainable..."
Fang Cheng looked at the slightly deford 20kg dumbbell in his hand, feeling secretly relieved.
Fortunately, the degree of deformation wasn’t too excessive.
Otherwise, dealing with such an item would indeed be a bit troubleso.
Setting down the tornted dumbbell, Fang Cheng gently flicked his hand and refocused his gaze on the panel.
Looking at the second effect content introduction of "Absolute Control."
"Specialization in climbing ability, fingertip surface area friction enhanced by 1000%..."
Fang Cheng read softly, a trace of curiosity flickering in his eyes>.
After thinking for a mont, he unclasped the barbell plates used for weight training from his waist, creating a clanging sound.
Then he stretched his limbs and slowly walked to the wall, reaching out his fingers to lightly touch the pale blue latex-painted wall surface.
Zzzz——
The mont the fingertips touched the wall, a peculiar adhesive feeling instantly transmitted from the nerve endings.
It felt like billions of nanoscopic bristles grew on the fingertips, gripping onto the invisible tiny pores in the wall surface.
Through introspection, Fang Cheng could clearly sense a powerful electrostatic attraction at a microscopic level generated the instant his fingers touched the wall.
