There are many varieties of push-ups:
Close-grip pushups: To perform close-grip pushups, place your hands closer together than shoulder-width apart. This will increase the challenge on your triceps.
Wide-grip pushups: To perform wide-grip pushups, place your hands further apart than shoulder-width apart. This will increase the challenge on your chest muscles.
Elevated pushups: To perform elevated pushups, place your feet on an elevated surface such as a step or bench. This will increase the difficulty of the exercise.
Plyometric pushups: Plyometric pushups, also known as "clap" pushups, involve pushing up with enough force to lift your hands off the ground and clap them together before returning to the starting position.
One-armed pushups: As the name suggests, one-armed pushups are performed using only one arm. They are an advanced variation that requires a high level of upper body strength.
Knuckle pushups: Knuckle pushups are performed with your hands in a fist position, with your knuckles facing down. They are a more challenging variation that places more of the load on your wrists and forearms.
Diamond pushups: Diamond pushups are performed with your hands placed close together, forming a diamond shape with your index fingers and thumbs. They are a challenging variation that targets the triceps muscles.
