How often do you wake up in a cold sweat in the middle of the night thinking, “If only I could put on one more inch on my arms,” or “Will my gym crush finally talk to me if I curl 60-pound dumbbells?” Okay, the yearning to impress the cutie in the gym might be exclusive to me, but can you put your hand on your heart and say you’ve never wanted bigger arms?
Unlike legs, arms are one of the most loved muscle groups to train, and yet only a handful of people have guns worth showing off. Most lifters cannot build size in their arms because they tend to oversimplify arm training.
Curling more often and heavier might not always be the most optimal way of beefing up your arms. People usually perform the same training routine for months and still blame the god of gains for their growth stagnation inside the gym. If you have hit a muscle or strength plateau, you need to rejig your training approach to break through the overhead ceiling. Remember, it is easier to avoid hitting a plateau than smashing through it.
Most arm training articles on the internet give you a single workout to perform for 12 weeks, which can get boring and often causes lifters to give up on their python-building goals. This article is different. We have put together eight arm-blasting workouts that will help you take your gains to the next level.
Before getting into the workouts, let’s go over the human arm anatomy. Learning about different arm muscles will help you learn how they work and decide between different exercises to train them optimally. For example, if you have lagging triceps, following a biceps-focused workout program will only widen your muscular imbalance. Additionally, understanding the structure of your arms will help you better utilize different grips and patterns of movement.
Muscle Anatomy — Biceps
To make the most of your arm workouts and ensure overall development, you need to focus on three bicep muscles — the biceps brachii, brachialis, and brachioradialis. Here is the difference between these muscles:
1. Biceps Brachii
Your biceps consists of two heads — the long and short head. The short head originates at the front of your scapula and inserts at top of the radius (the forearm bone that ends near your thumb). On the other hand, the long head also originates at the scapula but takes a longer route to insert into your radius.
The biceps brachii helps create supination and flexion. A supinated grip (palms facing forward) targets the brachii most effectively.
Brachialis lies underneath the brachii and runs from the midpoint of your humerus (upper arm bone) to your ulna (the forearm bone that ends near your pinky finger). It helps flex the elbows and can be targeted using hammer grip exercises.
The brachialis exercises can also make your biceps appear bigger by pushing your brachii up from below.
It is a long forearm muscle that originates on the humerus and attaches at the end of the radial bone. The brachioradialis is best trained using a pronated grip (palms facing your body). A fully pronated grip loses the mechanical advantage of the biceps, giving you a direct line of pull to the brachioradialis.
Muscle Anatomy — Triceps
Although triceps make up the majority of your upper arm, they do not get the same amount of love as their siblings on the other side of the arm. Triceps are made up of three heads — lateral, medial, and long. A fully developed tricep looks like a horse kicked you in the back of your arm.
1. Lateral Head
Lateral Head originates on the upper humerus and attaches to your elbow. Extension movements where your arms are under your shoulder level work all three tricep heads equally.
2. Medial Head
The medial head starts on the backside of the humerus and attaches to your elbow.
3. Long Head
The inner-tricep head runs from your scapula and attaches to your elbow. Overhead tricep extension exercises isolate the long head of your triceps.
Resistance exercises can be categorized into two sections —
- Compound movements: Compound (multi-joint) lifts like barbell bicep curls are effective in building strength, muscle mass, and improving overall functionality. Additionally, these exercises require more balance and coordination compared to isolation lifts.
- Isolation movements: These are single-joint lifts like the cable tricep pressdown that help in improving muscle definition and symmetry.
If your goal is to build arms that could match Arnold Schwarzenegger’s mountain peaks, you need to incorporate both types of exercises in your arm workouts. 
Eight Arm Workouts For Building Venomous Pythons
In the workouts below, you’ll be using at least one advanced training technique in every training session to ensure your muscles never get used to your training style. You could cycle through the eight arm workouts for the next eight weeks, or bookmark this page and come back to it later when you are looking for a workout that will leave you sore for days.
Now that you know everything there is to know about arm training, let’s dive into the eight workouts that will help you turn your guns into bazookas.
Arm Workout #1
- Barbell Bicep Curl: 4 sets of 10-15 reps, 30-sec rest — last set will be a double-dropset
