An arm workout refers to a type of exercise routine that specifically targets and works out the muscles in your arms, including those in your shoulders, biceps, triceps, and forearms. This can help build strength, tone up the area, and improve overall upper body mobility and flexibility. Arm exercises can be done using various equipment such as dumbbells or resistance bands, or through bodyweight movements like push-ups or pull-ups. A well-rounded arm workout typically includes a combination of compound exercises that engage multiple muscle groups (such as bench presses and bent over rows), isolation exercises for specific muscles (like bicep curls and tricep extensions), and movements to target the smaller stabilizing muscles in your arms like shoulder presses or reverse flys.
