The activity you are referring to is likely a wall push-up. This exercise involves placing your palms flat against a wall at shoulder height and performing a push-up motion by leaning your body towards the wall and then pushing back. It is a modified version of a traditional push-up that can be used to build strength in the chest, shoulders, and arms.
This activity is called a wall push. It is a simple bodyweight exercise that primarily works the chest, shoulders, and triceps muscles. It helps to build upper body strength and endurance.
The equal and opposite reaction is the wall pushing back against you. When you hit the wall with a stick, the force you exert on the wall is transferred to you through the stick, causing the wall to push back with an equal force. The stick simply transmits this force between you and the wall.
The force is typically due to the muscles in your fingers contracting and exerting a pushing force against the wall, resulting in your fingers bending. This force is a result of the interaction between your muscles and the wall, known as the normal force.
The force that causes your fingers to bend when pushing against a wall is the normal force exerted by the wall acting in the opposite direction. This force counteracts the force you apply with your fingers, resulting in compression and bending of your fingers.
When a person leans against a wall, the wall exerts an equal and opposite force on the person, as described by Newton's third law of motion. This means that the force exerted by the person on the wall is matched by an equal force exerted by the wall on the person in the opposite direction.

Pressing your palms against a wall with full force is an isometric exercise, where you engage your muscles to generate tension without joint movement. This activity can help strengthen your arms, shoulders, and chest muscles.
The normal force is equal in magnitude but opposite in direction to the force applied against the wall. If the object is held against the wall with a force, then the normal force acting on the object will be equal in magnitude to that force. If the mass of the object is given, you can calculate the force needed to hold it against the wall using Newton's second law (F = ma).

When a ball hits a wall, the force of the ball hitting the wall (impact force) pushes against the wall, while the wall exerts an equal and opposite force back on the ball (reaction force).
If you push against a wall, the wall will exert an equal and opposite force back against you, according to Newton's third law of motion. Therefore, you will not be able to move the wall. The force you apply will result in either the wall moving if it is not fixed, or you using energy without moving the wall.
