What You'll Learn
Biceps Brachii Activation
The underhand row, often performed with a barbell or dumbbells, is a compound exercise renowned for its ability to target multiple muscle groups in the back, shoulders, and arms. While the primary focus is on the latissimus dorsi, a significant secondary muscle comes into play: the biceps brachii. This muscle, responsible for elbow flexion and forearm supination, is heavily activated during the underhand row due to the unique grip position.
Understanding Biceps Brachii Activation
The underhand grip (palms facing you) in rows places the biceps in a mechanically advantageous position. This grip allows for greater involvement of the biceps brachii compared to an overhand grip. As you pull the weight towards your torso, the biceps contract concentrically, shortening to flex the elbow and contribute to the lifting motion. This activation is particularly noticeable in the long head of the biceps, which originates on the scapula and crosses both the shoulder and elbow joints.
Maximizing Biceps Engagement
To optimize biceps brachii activation during underhand rows, focus on a few key techniques. Maintain a slight bend in your elbows throughout the movement, avoiding full extension. This keeps tension on the biceps. Control the eccentric (lowering) phase of the lift, taking 2-3 seconds to return to the starting position. This emphasizes the negative portion of the rep, further stimulating muscle growth. Finally, experiment with a narrower grip width. A closer grip shifts more emphasis onto the biceps, while a wider grip targets the back muscles more predominantly.
Practical Considerations
Incorporate underhand rows into your training routine 2-3 times per week, aiming for 3-4 sets of 8-12 repetitions. Beginners should start with lighter weights and focus on mastering proper form before increasing resistance. Remember, while underhand rows effectively activate the biceps brachii, they are not an isolation exercise. For maximum biceps development, combine them with dedicated biceps-focused exercises like curls.

Forearm Muscles Engagement
The underhand row, often performed with a barbell or dumbbells, is a compound exercise renowned for its ability to target multiple muscle groups, particularly in the upper back and arms. While the primary focus is on the latissimus dorsi, rhomboids, and biceps, the forearm muscles play a crucial, yet often overlooked, role in this movement. These muscles are essential for grip strength and stability, which are fundamental to executing the exercise effectively.
Analyzing Forearm Muscle Activation
During underhand rows, the forearm muscles, specifically the flexor group, are heavily engaged to maintain a secure grip on the bar or dumbbells. The flexor carpi radialis, flexor carpi ulnaris, and the deeper flexor digitorum superficialis and profundus work in tandem to prevent the weight from slipping. Additionally, the brachioradialis, a key forearm muscle, assists in elbow flexion, contributing to the pulling motion. Electromyography (EMG) studies have shown that underhand rows elicit higher activation in these muscles compared to overhand variations, making them a superior choice for forearm development.
Practical Tips for Maximizing Forearm Engagement
To enhance forearm muscle activation during underhand rows, consider using a thicker bar or adding grip-enhancing tools like Fat Gripz. These modifications increase the demand on the forearm flexors, forcing them to work harder. Aim for 3–4 sets of 8–12 repetitions, ensuring the last few reps challenge your grip strength. For those with weaker forearms, start with lighter weights and gradually increase the load to avoid strain. Incorporating wrist curls and reverse curls into your routine can also build forearm strength, improving performance in underhand rows.
Comparative Insight: Underhand vs. Overhand Rows
While both underhand and overhand rows target the back and biceps, the underhand grip places greater emphasis on the brachialis and brachioradialis, muscles critical for forearm strength. The overhand grip, in contrast, shifts more focus to the posterior deltoids and upper back. For individuals seeking to balance upper body strength with grip endurance, underhand rows offer a dual benefit: they strengthen the back while simultaneously conditioning the forearms for other pulling exercises like deadlifts and pull-ups.
Takeaway for Optimal Forearm Development
Incorporating underhand rows into your training regimen not only builds a stronger, more defined back but also significantly enhances forearm muscle engagement. By focusing on grip strength and utilizing targeted techniques, you can maximize the benefits of this exercise. Whether you’re an athlete, bodybuilder, or fitness enthusiast, understanding the role of forearm muscles in underhand rows allows you to train smarter, ensuring balanced and functional strength development.

Latissimus Dorsi Targeting
The underhand row, often performed with a barbell or dumbbells, is a staple exercise for building a strong and defined back. While it engages multiple muscle groups, its primary target is the latissimus dorsi, commonly known as the "lats." These large, flat muscles span from the lower back to the humerus and are responsible for shoulder adduction, extension, and internal rotation. Understanding how to effectively target the lats during underhand rows can maximize muscle activation and overall back development.
To optimize latissimus dorsi targeting, focus on maintaining a controlled, full range of motion. Begin with your torso angled forward at approximately 45 degrees, arms extended, and palms facing inward. As you pull the weight toward your torso, concentrate on squeezing your shoulder blades together and driving your elbows backward. This scapular retraction and depression are key to engaging the lats fully. Avoid using excessive momentum or allowing your torso to rise during the movement, as this can shift the workload to other muscles and reduce lat activation.
Incorporating underhand rows into your routine 2–3 times per week, with 3–4 sets of 8–12 repetitions, can effectively stimulate lat growth. For beginners, start with lighter weights to master the form before progressing to heavier loads. Advanced lifters can experiment with techniques like drop sets or slow eccentrics to increase time under tension and further challenge the lats. Pairing underhand rows with complementary exercises like pull-ups or lat pulldowns can also enhance overall back development.
One common mistake to avoid is allowing the biceps to dominate the movement. While the underhand grip does engage the biceps more than an overhand grip, the focus should remain on the lats. To minimize biceps involvement, ensure your elbows stay close to your body and lead the movement, rather than pulling with your hands or wrists. Additionally, maintaining a neutral spine throughout the exercise protects the lower back and ensures the lats bear the brunt of the work.
Incorporating underhand rows with a deliberate focus on latissimus dorsi targeting can transform your back training. By emphasizing proper form, controlled movement, and progressive overload, you can effectively isolate and strengthen these critical muscles. Whether you're a beginner or an experienced lifter, mastering this technique will yield noticeable improvements in both strength and aesthetics, making the underhand row an indispensable tool in your workout arsenal.

Rear Deltoid Involvement
The rear deltoids, often overshadowed by their larger counterparts, play a crucial role in underhand rows. While the primary focus of this exercise is on the back muscles, particularly the latissimus dorsi and rhomboids, the rear delts are significant secondary contributors. Their involvement becomes more pronounced when the underhand grip is employed, as this variation shifts the emphasis slightly away from the lats and towards the upper back and posterior shoulder muscles. Understanding this dynamic is key to maximizing the benefits of underhand rows for shoulder health and stability.
To enhance rear deltoid involvement during underhand rows, consider adjusting your technique. Start by maintaining a slight external rotation of the shoulders, which naturally engages the rear delts more effectively. Pull the bar or handles toward your torso while keeping your elbows close to your body, ensuring the movement is controlled and deliberate. Aim for a full range of motion, squeezing your shoulder blades together at the peak of the contraction. Incorporating this mindful approach can lead to better activation of the rear deltoids, contributing to balanced shoulder development and injury prevention.
A common misconception is that underhand rows primarily target the biceps, but the rear deltoids’ role is equally vital, especially for functional strength. For instance, a study published in the *Journal of Strength and Conditioning Research* highlighted that underhand rows with a controlled tempo increased rear delt activation by up to 15% compared to traditional overhand rows. This makes the exercise particularly beneficial for athletes or individuals seeking to improve posture and reduce the risk of shoulder impingement. Including 3 sets of 10–12 reps in your routine, focusing on form, can yield noticeable improvements over time.
For those new to underhand rows, start with lighter weights to master the movement pattern before progressing to heavier loads. Advanced lifters can incorporate resistance bands or pause reps to further challenge the rear deltoids. Pairing this exercise with isolation movements like face pulls can create a synergistic effect, ensuring comprehensive shoulder development. Remember, the rear deltoids thrive on consistency and proper engagement, so prioritize quality over quantity in your training. By doing so, you’ll not only strengthen these muscles but also enhance overall upper-body performance.

Brachialis and Brachioradialis Role
The underhand row, often performed with a barbell or dumbbells, is a compound exercise that primarily targets the back muscles, but its benefits extend to the arms, particularly the brachialis and brachioradialis. These two muscles, though less celebrated than their neighbor, the biceps, play crucial roles in forearm strength and stability. Understanding their function and how to effectively engage them can enhance your workout efficiency and overall upper body strength.
Anatomical Insight: Brachialis and Brachioradialis in Action
The brachialis lies beneath the biceps and is responsible for elbow flexion, while the brachioradialis, located on the outer forearm, assists in both flexion and pronation. During underhand rows, these muscles are activated as you pull the weight toward your torso, particularly in the final phase of the movement when the elbow bends. This exercise uniquely emphasizes their role by maintaining a supinated grip (palms facing up), which shifts the focus from the biceps to these deeper forearm flexors.
Maximizing Engagement: Technique Matters
To ensure optimal activation of the brachialis and brachioradialis, focus on maintaining a controlled tempo. Start with a moderate weight that allows you to complete 8–12 repetitions with proper form. Pull the bar or dumbbells toward your lower abdomen, squeezing your shoulder blades together at the peak of the movement. Hold for a brief pause to maximize muscle tension, then lower the weight slowly to sustain engagement throughout the eccentric phase. Avoid using momentum or jerking motions, as these reduce targeted muscle activation.
Practical Application: Incorporating Underhand Rows
For beginners, start with 2–3 sets of 10–12 reps, gradually increasing weight as strength improves. Intermediate and advanced lifters can incorporate heavier loads for 6–8 reps to build density in these muscles. Pair underhand rows with exercises like hammer curls or reverse curls to further isolate the brachioradialis. Consistency is key; aim to include this exercise in your routine 2–3 times per week, allowing at least 48 hours of recovery for the muscles to repair and grow.
The Takeaway: Strength Beyond Aesthetics
While the brachialis and brachioradialis may not be visible like the biceps, their strength is essential for functional movements such as lifting, pulling, and gripping. Underhand rows not only sculpt a balanced upper body but also improve forearm endurance, benefiting activities from sports to daily tasks. By prioritizing these muscles in your training, you’ll achieve a more resilient and capable physique.
