Best Arm Workouts for Big Arm to Build Muscle with Equipment

Introduction

Not only are well-developed arms attractive, but they also play a big role in total strength and a muscular, well-balanced body. Robust biceps and triceps are essential for numerous arm workouts or compound workouts, including pull-ups, rows, and presses, since they help with weightlifting and stability.

Additionally, well-sculpted arms can draw attention to your hard work in the gym and improve the overall aesthetic attractiveness of your physique. Beyond only gaining larger muscles, arm resistance exercise has many more advantages.

It strengthens the grip, which benefits various everyday chores and sports. Because strong arms support the shoulder joints, so they help improve posture and reduce the chance of injury. 2022 study by MDPI Nutrients^[1], Resistance exercise also increases metabolism, which increases calorie burning even when you’re at rest.

Anatomy of the Arms

A. Muscles involved

Biceps

The most noticeable muscle on the front of the upper arm is the biceps brachii, which has two heads: a long head and a short head. These heads are put into the radius bone of the forearm from the shoulder blade.

Flexing the elbow joint is accomplished by the brachialis muscle, which is located beneath the biceps brachii^[2].

Triceps

The big muscle on the rear of the upper arm is called the triceps brachii^[3]. The long head, lateral head, and medial head are its three heads.

These heads attach to the ulna bone in the forearm after originating from the shoulder blade and the humerus (upper arm bone). The elbow joint’s extension is the main purpose of the triceps.

Forearms

Wrist flexors and extensors, two muscles that enable wrist and hand movements, are part of the forearms. The brachioradialis, which is found on the outside of the forearm, helps with forearm rotation and elbow flexion^[4].

B. Functions of each muscle group

The main muscles that flex the elbow joint and enable curling motions are the brachial and brachialis biceps. They also help in supination, which is the rotation of the hand and forearm palm up, and shoulder flexion.

The primary muscle involved in extending the elbow joint, which is essential for pushing motions like pushes and extensions, is the triceps brachii. Strong grip and dexterity are made possible by the forearm muscles, which also regulate wrist and hand movements.

Structuring an Arm Workouts

A. Number of sets and reps for different goals

Strength gains: To increase arm strength, aim for 4-6 repetitions using heavier weights. This low-rep range encourages neural adaptations and enhanced muscle activation, allowing you to lift more weight.

Hypertrophy (muscle building): To optimize muscle growth, a moderate rep range of 8–12 reps is recommended. This range enables you to lift weights that are difficult enough to test your muscles and build up enough volume to encourage muscular growth.

Muscular endurance: Choose greater repetition counts of 12–15 reps or more if you aim to increase your arms’ muscular endurance. This greater rep range will increase the muscles’ capacity for endurance by testing their ability to execute repeated contractions

B. Exercise order and selection

It is recommended to begin an arm workout with complicated exercises like presses and rows that train many muscle groups. By working the major muscular groups as well as the arms, these workouts enable you to lift more weights and increase overall muscle activation.

Proceed to isolation exercises^[7] that focus on particular arm muscles, such as triceps extensions and biceps curls, after compound workouts.

With these workouts, you can intensify your arm fatigue while concentrating on the targeted muscle region. To facilitate active recovery and effective use of rest intervals, it is also advised to switch up your biceps and triceps exercises.

C. Sample arm workout routine

• Dumbbell overhead press: 4 sets of 6-8 reps
• Seated dumbbell biceps curl: 3 sets of 10-12 reps
• Triceps dip: 3 sets of 10-12 reps
• Standing dumbbell hammer curl: 3 sets of 10-12 reps
• Overhead triceps extension: 3 sets of 10-12 reps
• Forearm wrist curls: 2 sets of 15-20 reps

Warm-up and Preparation Before Arm Workouts

A. Importance of warming up before arm workouts

Warming up before arm workouts is crucial to prepare your muscles, joints, and nervous system for the intense work ahead. A 2018 study Journal of Exercise Rehabilitation^[8] mentioned, proper warm-up increases blood flow raises core temperature, and improves mobility, reducing the risk of injury and optimizing performance.

B. Arm warm-up circuit

• Arm circles (10-15 reps in each direction)
• Bodyweight squats (10-15 reps)
• Pushups (10 reps)
• Arm swings (10-15 reps in each direction)
• Wrist circles (10-15 reps in each direction)
