Meta Description:
Learn the location and function of the biceps brachii and follow three simple, science‑backed bodybuilding workouts to grow stronger, fuller biceps. Includes illustrations, videos, FAQs, and APA references.
Introduction To Bodybuilding Workouts To Sculpt The Biceps
If you want bigger, stronger, more defined arms, the biceps brachii is one of the most important muscles to train. Whether you're a beginner or an experienced lifter, understanding how the biceps work — and choosing exercises that match their anatomy — will help you build muscle faster and avoid injury.
This guide breaks everything down in simple, friendly language, backed by real anatomical science. You’ll learn:
- Where the biceps brachii is located
- What it actually does
- Why certain exercises grow it better
- Three simple, science‑supported workouts
- Illustrations and videos to help you learn visually
Let’s start with the basics.
Biceps Brachii: Location, Structure & Function
Where is the Biceps Brachii Located?
The biceps brachii is a two‑headed muscle located on the front of your upper arm, between your shoulder and elbow.
Biceps Brachii Heads
1. Biceps Brachii Long Head: Originates at the supraglenoid tubercle of the scapula
The supraglenoid tubercle is just a tiny bump at the top of your shoulder blade (the scapula). Think of it as the upper anchor point where the long head of the biceps starts.
It’s tucked deep inside the shoulder joint, helping the biceps connect your upper arm to your shoulder.
👉 Simple version:
The long head of the biceps starts from a small spot at the top of your shoulder blade, inside the shoulder joint.
Biceps Brachii Short Head: Originates at the coracoid process of the scapula
The coracoid process is a small hook‑like projection on the front of your shoulder blade.It sticks out slightly under the collarbone and serves as a strong attachment point for several muscles, including the short head of the biceps.
👉 Simple version:
The short head of the biceps begins from a little hook‑shaped part of your shoulder blade, just under your collarbone.
Biceps Brachii Insertion:
The tendon also spreads out into a thin sheet called the bicipital aponeurosis, which helps support the forearm and protects the structures in the elbow.”
What Does the Biceps Do?
The biceps brachii performs three major actions:
- Forearm supination (turning your palm upward) — its strongest function
- Elbow flexion (bending the arm)
- Shoulder flexion (helps lift the arm forward)

3 Simple, Science‑Backed Biceps Workouts
Below are three beginner‑friendly workouts based on how the biceps actually function. Each includes step‑by‑step instructions, illustrations, and videos.
1. Standing Dumbbell Supinated Curl (Palm‑Up Curl)
Why The Standing Dumbbell Supinated Curl Works (Science)
The biceps is strongest when the forearm is supinated (palm up). This exercise maximizes tension during both elbow flexion and supination.

How to Do The Standing Dumbbell Supinated Curl (Step‑by‑Step)
- Stand tall holding dumbbells at your sides, palms facing forward.
- Keep elbows close to your torso.
- Curl the weights upward while keeping palms facing up.
- Squeeze the biceps at the top.
- Lower slowly for 3–4 seconds.
Standing Dumbbell Supinated Curl Reps & Sets
- 3–4 sets of 8–12 reps
2. Hammer Curl (Neutral‑Grip Curl)
Why The Hammer Curl Works (Science)
Hammer curls target the brachialis and brachioradialis, which lie beneath the biceps. Strengthening these muscles pushes the biceps upward, making them look bigger.
Hammer Curls Tutorial Step-by-Step
- Hold dumbbells with palms facing each other.
- Curl upward while keeping elbows tight.
- Pause at the top.
- Lower slowly.
Hammer Curls Reps & Sets
- 3 sets of 10–12 reps
3. Incline Dumbbell Curl (Long‑Head Focus)
Why The Incline Dumbbell Curl Works (Science)
The incline position stretches the long head of the biceps, increasing muscle activation and promoting hypertrophy.
How to Do The Incline Dumbbell Curl
- Sit on an incline bench (45–60°).
- Let arms hang straight down.
- Curl both dumbbells upward without swinging.
- Lower slowly to full stretch.
Incline Dumbbell Curl Reps & Sets
- 3 sets of 8–10 reps

Frequently Asked Questions (FAQ)
1. How often should I train biceps?
2 times per week is ideal for most people.
2. How long until I see results?
Most beginners see visible changes in 4–6 weeks with consistent training.
3. Should I lift heavy or light?
Use a weight that allows 8–12 reps with good form — the best range for hypertrophy.
4. Why do my forearms get tired first?
Your brachioradialis and grip muscles may be weaker. Hammer curls help balance this.
5. Do I need machines?
No — dumbbells alone can fully develop the biceps.
