Underhand Barbell Row: Complete Guide to the Supinated Bent-Over Row
The underhand barbell row is a compound pulling exercise that targets the back muscles with an emphasis on the lower lats and biceps. By using a supinated (palms-up) grip on the bent-over barbell row, you shift the muscle recruitment pattern compared to the standard overhand variation, making it an excellent choice for building a thick, well-developed back.
Why Choose the Underhand Grip
The supinated grip in the underhand barbell row offers several advantages:
- Greater lat activation: The underhand grip allows a longer range of motion and deeper contraction of the latissimus dorsi
- Increased bicep involvement: The supinated position places the biceps in a mechanically stronger position
- Better lower lat engagement: The row path naturally targets the lower portion of the lats
- Reduced upper trap dominance: Less tendency to shrug the weight up compared to overhand rows
Muscles Worked
- Latissimus dorsi - the primary mover, especially the lower fibers
- Rhomboids and middle trapezius - scapular retractors that pull the shoulder blades together
- Biceps brachii - significantly engaged due to the supinated grip
- Posterior deltoids - assist in the pulling motion
- Erector spinae - stabilize the spine during the bent-over position
- Forearms - maintain grip on the barbell throughout the set
Step-by-Step Instructions
-
Setup: Stand with feet shoulder-width apart. Grip the barbell with an underhand grip (palms facing away from you), hands slightly wider than shoulder width.
-
Hinge forward: Push your hips back and bend at the waist until your torso is roughly 45 degrees to the floor. Keep your back flat and core braced. Let the bar hang at arm's length.
-
Row the bar: Pull the barbell toward your lower stomach, driving your elbows back and squeezing your shoulder blades together. The bar should travel in a straight line toward your navel.
-
Peak contraction: Hold the top position for one second, focusing on squeezing the lats and rhomboids.
-
Lower with control: Slowly extend your arms to return the bar to the starting position. Maintain your hip hinge throughout the entire set.
Common Mistakes to Avoid
- Rounding the lower back: This is the most dangerous mistake. Keep a neutral spine by bracing your core and maintaining the hip hinge.
- Standing too upright: A torso angle closer to vertical turns this into an upright row. Stay bent over at approximately 45 degrees.
- Using momentum: Jerking the weight up with body English reduces muscle tension. If you need momentum, the weight is too heavy.
- Pulling to the chest: The underhand row should target the lower stomach. Pulling too high shifts emphasis away from the lower lats.
- Grip too narrow or too wide: Shoulder-width or slightly wider provides the best balance of lat and bicep engagement.
Variations of the Underhand Row
- Pendlay underhand row: Each rep starts from the floor with a dead stop, reducing momentum
- Underhand dumbbell row: Allows unilateral training and greater range of motion
- Underhand cable row: Provides constant tension throughout the movement
- Underhand T-bar row: Allows heavier loading with a more stable setup
Programming Recommendations
The underhand barbell row fits well as a primary or secondary back exercise:
- For back thickness: 4 sets of 6-8 reps with heavy weight after deadlifts
- For muscle building: 3-4 sets of 8-12 reps as a primary pulling movement
- For endurance and pump: 3 sets of 12-15 reps with controlled tempo
This exercise pairs well with vertical pulling movements like pull-ups or lat pulldowns for complete back development. The combination of horizontal and vertical pulling ensures all fibers of the lats are trained.
Safety Considerations
Because the bent-over position places significant stress on the lower back, lifters with existing back issues should approach this exercise with caution. Using a weightlifting belt for heavy sets and keeping the core braced throughout each rep are essential safety practices. If back discomfort occurs, switch to a chest-supported row variation that removes spinal loading.
