Depends on which muscle it is. but the answer is (Muscle Strength) -apex
Exerting force in a porportional manner, not using too much or too little force.
It's called the stretch reflex and involves muscle spindles which are sensorimotor organs located in skeletal muscle.

The desk is exerting a gravitational force, equal in magnitude but opposite in direction to the force of gravity acting on the book. This force has a magnitude of 4.9 newtons (N) downwards, as gravity pulls objects with a force of 9.8 N/kg and the book has a mass of 0.5 kg.
Because the force of gravity exerting on objects on the moon is much lower than that of the earth.
Exercising increases muscle sizes by exerting pressure on these muscles (but not too much mind). As a response the muscle tenses to allow the increase of weight being lifted (relating to the arms) for example to allow the body to develop as an adaptation tool used by our earlier ancestors to survive.
Assuming the dumbbell is suspended at a constant height from the ground and not moving you are exerting 89 Newtons (N). Force (N) = Mass (kg) x Acceleration due to gravity (9.8067 m/s2) 20lb = 9.072 kg 9.072 x 9.8067 = 89 N Leigh
The amount of gravity something has is determined by its mass and how close it is to other objects exerting gravitational force. The more massive an object is, the more gravitational force it can exert, and the closer two objects are, the stronger the gravitational force between them.
A muscle contraction happens when too much force or stress is forced upon a muscle cavity. Dr. Whitmore PHD
Strength is the definition word for "amount of force a muscle exerts.[shally]
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
The amount of gravity pulling on an object depends on its mass and the mass of the object exerting the gravitational force. The greater the mass of the object, the stronger the gravitational force it exerts. The force of gravity weakens with distance, following the inverse square law.
