Arm Day

What is arm day in fitness?

Workout day specializing on arms

Arm day is a fitness slang term for workouts that focus on arms. It's a variation of the leg day phrase that fitness fanatics use to refer to their leg workouts.

The workouts on Arm day target the biceps, triceps, deltoids, and pectoral muscles. Examples of these workouts include barbell bicep curls, cable triceps pushdowns, and dumbbell preacher curls.

Fitness enthusiasts often use "arm day" on social media when boasting about the size of their arms or making fun of people who skipped arm day (their upper body muscles are lacking). However, even non-fitness fans have become aware of the term since it became popular on social media in the 2010s and use it, mostly online and sarcastically.
