Forearm Muscles

The Forearm Muscles

The forearm muscles are the muscles on your lower arm, and you use them whenever you open or close your hand or when your move your wrist. Mostweight lifters and bodybuilders who work a lot with free weights or bodyweight exercises don't need additional forearm exercises, because when you curl up a dumbbell or hold on a barbell, your forearm muscles already get a great workout. However, some people want to focus on their forearm muscles and gymnasts need stronger forearms than the average athlete - to protect their wrists from injuries. Below you will find general information about the forearm muscles and a few exercises. Find more exercises and information about other muscle groups, check out weight training main.

Advice

  • Some free weight exercises and many bodyweight exercises actually train the forearms better than some forearm exercises. For example the chin up, where you have to hold on a bar, or the alternating dumbbell curl, where you have to keep your wrist straight, are great forearm exercises.
  • Stretch your forearms between sets and exercises. I recommend to stretch the forearms whenever they feel tight after a heavy exercise.
  • Forearm exercises are not made for low reps (low reps = few repetitions). Do between 25 and 50 repetitions per set and don't forget to stretch between sets and exercises.
