Arm day should be a bodybuilder's happiest day of the week. So, is it yours? If not, maybe your workout is to blame. You should be excited to head to the gym, confident that you're making progress, and looking forward to a serious pump. I've got you covered with the best biceps and triceps workouts from my little black book.



Meet your detailed blueprint of how to build huge arms. Along with a growth-focused approach to nutrition and supplementation, this is what you need to grow the muscles you really want to show off!

Know Your Arms to Grow Your Arms

When someone asks you to show your muscles, you flex your biceps. But your triceps actually make up 2/3 of your arm mass! Many beginners fall into that trap—even the great Arnold Schwarzenegger has admitted he trained his biceps harder and more often than his triceps in the beginning. This built an imbalance that took him years to balance back out.

Here's the best way to build bigger arms: hit biceps and triceps equally hard, using all kinds of rep ranges from high (15-20) to moderate (8-12) to low (4-6). For the first eight weeks of this program, you'll train triceps before biceps! Here's what you need to know about each group:

Biceps Muscles: The major function of your biceps muscles is to bend or "flex" your elbow. When you want to build them, your approach should include variations on the best biceps exercises from multiple angles:  

Biceps curl

Because your biceps also function as forearm rotators, you should include multiple grip styles:  

  • Palms up: traditional curls
  • Palms in: hammer curls
  • Palms down: reverse curls

No, you don't need to do all those styles and grips in every workout! Just cycle through the workouts below over a course of months and you'll be covered.

Triceps Muscles: Your triceps are the counterpoint to your biceps and extend or straighten the elbow. The best triceps exercises also cover a range of angles to hit all three "heads" of this muscle group.



  • In front of your body: close-grip bench press or push-downs
  • In front of your face: skullcrushers
  • Over your head: overhead cable extensions
Triceps cable rope push-down

Forearm Muscles: Your forearms are responsible for your grip strength, as well as your wrist stability and strength. If you've been ignoring forearm workouts so far in your training, get ready to be seriously challenged! You'll perform seriously high-rep sets—like 50 reps per set!

Next-Level Arm Training in Three Workouts a Week

Bodybuilder Julian Smith has arm training down to a science. In his popular program Killer Arms, you'll hit biceps one day, triceps another, and then blow it out with a bis-and-tris superset later in the week. Life is too short to have small arms!

How to Use These Workouts

Perform one dedicated arm workout per week, preferably on a Friday or Saturday. Your arms get hit adequately in chest, shoulder, and back workouts earlier in the week, so doing two rounds isn't necessary!

Perform Workout 1 once a week for 4-6 weeks, then move to Workout 2. Keep going until you get through Workout 5. Once you're through Workout 5, you can start over with Workout 1 confident that you're bigger and stronger than you were before.

While you're on this program, use Bodybuilding.com's macronutrient calculator to make sure you're eating enough calories, protein, carbs, and fats to support your goal of muscle gains. To grow your arms, you must be in a caloric surplus, meaning that you are eating more calories than you burn.

Along with protein, a couple of key supplements to consider with these workouts are:
