That's correct. Work is only done when a force causes an object to move in the direction of the force, so pushing against a stationary object, like a wall, does not result in any work being done.
Work is calculated as force multiplied by displacement in the direction of the force. In this scenario, since the wall doesn't move, there is no displacement in the direction of the force. Therefore, no work is done on the wall.
According to Newton's third law, the wall will push back against you with an equal force in the opposite direction.
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 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.
When you push on a wall, the wall exerts an equal and opposite force back on you, according to Newton's third law of motion. This reaction force is what gives you the feeling of the wall pushing back against you.

If you pushed as hard as you could against a wall while wearing roller skates, you would likely slide backward due to the force of your push. The friction between the skates and the floor may not be enough to keep you stationary, causing you to lose balance. The intensity of the push and the surface conditions would determine how far you slide back.

when you push your hand against a wall the wall is 'pushing' against you that is why you feel your hand being pushed.
When you push on a wall, the wall exerts an equal and opposite force back on you, according to Newton's third law of motion. This reaction force is what gives you the feeling of the wall pushing back against you.
It's because that it needs a cell wall to push against and an animal cell doesn't have one therefore nothing to push against.
When you push against a brick wall, the wall exerts an equal and opposite force back on you, as per Newton's third law of motion. The wall does not move because it has a much greater mass and inertia compared to you. Your effort is mostly expended on compressing your own muscles and joints, leading to fatigue.
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.
An example of an action that does no work would be pushing on a stationary wall. Despite applying force to the wall, since the wall does not move, no work is done as defined in physics (work = force applied * distance moved in the direction of the force).
