Of course it is, when you perspire it is one of the body's methods of cooling down as the sweat then evaporates and causes a cooling effect. Therefore, the more effort you exert, the hotter you become and consequently the more you perspire in order to cool down.
While this isn't an incredibly biological explanation I hope it still expresses that it is natural.
"Elbow grease" was first used in the early 17th century to refer to the physical effort and hard work required to clean or polish something by hand. The term suggests that one must exert a great deal of effort, as if using only the power of their elbows.

Basketball - Players exert a force when dribbling, passing, or shooting the ball, which changes the ball's velocity. Swimming - Swimmers exert force against the water to propel themselves forward, changing their velocity in the pool. Football - Players exert force when kicking or throwing the ball, resulting in a change in the ball's velocity.
Oh come on, middle school Biology isn't so hard that you can't list 10 plants. If you can exert the time and effort necessary to ask the question online, you can exert the time and effort to find the information about 10 plants.
From the magnet.
According to Selye, a person exerts an all-out effort to combat stress at the interface between the alarm reaction and the stage of resistance.

The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
The effort force is the force applied by you to move an object. It is the force you exert when pushing or pulling an object. The magnitude of the effort force depends on the weight and size of the object being moved.
Labor, exert.
its called i have a big smilke
A hand cart is a 1st class lever because the fulcrum (pivot point) is between the effort (person pushing or pulling) and the load (goods being carried). This allows the person to exert force over a distance to move a heavier load with less effort.
Unlike conventional garden tools, the unique ratchet mechanism allows the user to exert maximum leverage with minimum effort.
