Get Big Arms: Noah Siegel's Sleeve-Busting Workout

Get the horseshoe triceps, baseball biceps, and hulking forearms you always wanted. This short, high-intensity workout will show you the way!

I've seen countless people come into the gym and throw dumbbells around like potato sacks. They act wild, scream and grunt like gorillas in heat, and then spend their rest periods flexing in the mirror. Although these dudes seem hard-core, they're actually putting a lot of energy into something that won't garner results. They must learn to train smarter.

Many people fail to realize that they already train their arms multiple times per week, without ever doing any direct arm work. Every time we do a pressing movement, we use our triceps.

Every time we pull, we use our biceps and forearms. Because our biceps and triceps get a lot of work during compound movements, it's important to limit the number of sets during isolation work. With dedicated arm training, keep the sets low and the intensity high.

An even bigger problem is that most people don't understand anatomy well enough to train their biceps and triceps effectively. So to build big arms, we need to start by using our head.

How Your Arms Work ///

The major action of the biceps brachii is elbow flexion and forearm rotation. The name—biceps—means that the muscle is made of two heads, a long and a short. These muscle heads have two different origins but come together to form one tendon, which attaches to the radius.

You can feel your biceps working if you put your left and on your right biceps muscle and then rotate your forearm from a pronated (palm down) to a supinated (palm up) position. You can also feel your biceps participate if you put your left hand on your right biceps and flex your elbow.

Your biceps can fatigue easily, and thus relies on your front deltoid and brachioradialis (anterior forearm muscle) for aid. To get the most out of your biceps training, you need movements that include both flexion and supination.

The triceps brachii is named similarly because of its three heads. The triceps is a slightly larger portion of the arm and just as complex as the biceps. The triceps main function is to extend the elbow. To feel your triceps, place your left hand on the back of your right arm and then extend your right arm until it is completely straight. The long and lateral heads of the triceps create the "horseshoe" shape everyone is gunning for. The medial head is a "deep" muscle.

Not all three heads originate at the same place, but they all insert into the elbow. The long head of the triceps originates at the scapula. To isolate it, your elbow must be over your head.

Sleeve-Busting Arms Workout

    Now that I dropped some knowledge bombs, let's blow those arms up! Do this workout once per week on any day you choose. Generally, I do an abs/arms/forearms day later in the week after I've already worked my larger muscle groups.


  • Spider Curl Spider Curl

    Spider Curl

    4 sets: 12, 8, 6, 15 reps
  • Set the bench at a 45-degree angle and place your chest at the top of the bench. When you curl your arms up, don't raise your elbows. The last set should be relatively light.

  • Incline Dumbbell Curl Incline Dumbbell Curl

    Incline Dumbbell Curl

    3 sets: 8, 8, 6 reps
  • Curl with both arms at the same time, supinating your wrists as you go up. Lower the weights slowly. Go fairly heavy on this movement. If you do have to cheat, do it on the way up, so you can fight it on the way down.

  • Barbell Curl Barbell Curl

    Barbell Curl

    3 sets: 8, 8, 12 reps
  • Do this exercise with your back against a wall and your elbows down. Keep the eccentric portion slow and controlled. I find that biceps grow extraordinarily well on the negative work load.

  • Preacher Curl Preacher Curl

    Preacher Curl

    Dropset to failure
  • Load a bar with weight you can easily strip. Start with a weight you can hit for 12 reps. Then take off some weight and do as many reps as you can. Take off more weight, and do it again and again. By the end of this set, your biceps should be pretty much dead.


  • Triceps Pushdown Triceps Pushdown

    Cable Push-Down with Bar

    4 sets: 12, 8, 8, 8 reps
  • This is a staple in every triceps workout I do. Keep the body up straight and bend from the elbow only. Allow the arm to come up slightly past perpendicular. This exercise should be done as heavy as possible, including two dropsets.

  • Seated Triceps Press Seated Triceps Press

    Seated Triceps Press

    3 sets: 10, 8, 8 reps
  • This is a serious mass builder for the long head of the triceps. Go as heavy as you can. Don't let your elbows flare. Keep them tucked in tight.

  • Low Cable Triceps Extension Low Cable Triceps Extension

    Low Cable Triceps Extension

    3 sets: 12, 12, 15 reps
  • This exercise is similar to a standard dumbbell kick-back, but it keeps the tension on the triceps the entire movement. Be sure to keep the elbow up and to fully extend the arm back. Control the weight back to starting position.

  • Lying Dumbbell Tricep Extension Lying Dumbbell Tricep Extension

    Lying Dumbbell Tricep Extension

    3 sets: 15, 15, 20 reps
  • Use a dumbbell in each hand and press them simultaneously.


  • Seated Palms-Down Barbell Wrist Curl Seated Palms-Down Barbell Wrist Curl

    Seated Palms-Down Barbell Wrist Curl

    4 sets of 25 reps
  • Lay your forearms flat on the end of a bench so your hands are hanging off. Let the bar roll all the way down to the last finger tip and squeeze everything back up until your wrist is fully contracted.

  • Standing Palms-Up Barbell Behind The Back Wrist Curl Standing Palms-Up Barbell Behind The Back Wrist Curl

    Standing Palms-Up Barbell Behind The Back Wrist Curl

    3 sets: 15 reps
  • Use the straight bar. Place it behind you, just below your glutes. Let it roll down your hand and squeeze back up, fully contracting your wrists.

  • Reverse Barbell Curl Reverse Barbell Curl

    Reverse Barbell Curl

    3 sets: 15 reps
  • This movement hits my forearms hard. Keep it strict so you don't use your shoulders to lift the weight. Curl only from the elbow.

  • Hammer Curls Hammer Curls

    Hammer Curls (Optional finisher)

    1-2 sets: failure
  • If your body allows it, try them. You can be less strict with the form—throw weight around and just burn out those last fibers.

This workout provides more than sufficient arm work. Make sure to keep the intensity high and the pace quick. Hit them hard, hit them fast, and watch 'em grow!
