Push-ups are a basic but effective exercise for upper body strength. They can be done anywhere, at any time, and don't require any equipment.

Push-ups are also a good option for beginner exercisers because they can be modified to make them easier or more challenging. For example, beginners can start by doing push-ups on their knees instead of their toes.

As you get stronger, you can gradually work your way up to doing full push-ups with proper form. Push-ups can be part of a workout routine or they can be done as a standalone exercise. Doing a few push-ups every day is a great way to challenge yourself and see progress over time.
