Training arms refers to exercises that target the muscles of the upper arm, including the biceps and triceps. These workouts often involve movements like bicep curls, tricep extensions, and variations thereof. While training arms daily might seem like a good idea to some, it's generally not recommended. Muscles need time to recover and grow stronger after intense workouts, so training them daily can lead to overtraining and potentially hinder progress. Instead, it's more effective to give muscles at least 48 hours of rest between workouts to allow for proper recovery and adaptation.

It's important to incorporate arm training into your overall fitness routine because strong arms not only contribute to aesthetic goals but also play a crucial role in functional strength and everyday activities. However, the frequency and intensity of arm training should be balanced with other muscle groups and overall fitness goals. A well-rounded approach to fitness, including proper rest and recovery, will yield better results in the long run and reduce the risk of injury.
