The Best Back Exercises for Thickness and Width

The back is one of the largest and most complex muscle groups in the body — and one of the most commonly undertrained. Because you can't see your own back easily, it's easy to neglect. Because back exercises don't produce the same immediate visual feedback as chest or arm exercises, they're often underemphasized. Here's how to build a genuinely impressive back.

Back Anatomy: What You're Training

• •Latissimus dorsi (lats): The largest back muscle, responsible for the V-taper (back width). Runs from the upper arm down to the lower back. Trained by any pulling movement where the shoulder extends (pull-ups, pulldowns, rows with the arms below the shoulder)
• •Trapezius: The large diamond-shaped muscle of the upper back. Upper traps (shrug movement), middle traps (scapular retraction in rows), lower traps (pulling the shoulder blades down). Often the most visually prominent back muscle in developed physiques
• •Rhomboids: Between the spine and shoulder blades. Responsible for scapular retraction. Undertrained in most programs — directly targeted by face pulls and prone Y-raises
• •Erector spinae: The long muscles running alongside the spine. Critical for posture, spinal stability, and deadlift strength. Trained by all hinge movements
• •Rear deltoid: Technically a shoulder muscle, but trained in most back exercises. Contributes to the 3D, developed shoulder appearance

Exercises for Back Width (Lat Development)

• •Pull-up / Chin-up: The best back exercise, period. Weighted pull-ups are the strongest predictors of back development in natural athletes. Wide grip (shoulder-width or slightly wider) pulls from the lat; chin-up grip (supinated) increases bicep involvement and often allows more range of motion. Start with assisted pull-ups or lat pulldown if you can't complete 5 strict pull-ups
• •Lat pulldown (wide grip): The machine equivalent of pull-ups. Allows easy progression and is effective for people who can't yet pull their bodyweight. Focus on pulling the elbows toward your hips rather than pulling the bar to your chin
• •Straight-arm pulldown (cable): Isolates the lats by keeping the arms straight throughout. Removes bicep involvement and forces the lats to work alone — excellent for developing the mind-muscle connection and targeting the lower lats

Exercises for Back Thickness (Middle Back)

• •Barbell row (overhand or underhand): The primary back thickness builder. Heaviest loading of any back exercise. The bar should pull toward the lower abdomen with a near-horizontal torso to maximize lat and middle-back involvement
• •Dumbbell row (one-arm): Greater range of motion than the barbell row and allows each side to work independently. One of the most underrated back exercises — can be loaded extremely heavy relative to body size
• •Seated cable row (close or wide grip): Constant tension throughout the range of motion. The horizontal pull targets the middle back, rhomboids, and lower traps. Keep the torso upright and squeeze the shoulder blades at the end of the pull
• •Chest-supported row (machine or dumbbell): Removes the lower back from the equation — allows complete focus on the upper back muscles. Essential for people with lower back sensitivity
• •T-bar row: A classic back thickness builder that allows heavy loading in a comfortable position. The chest support version (landmine T-bar) is safer for the lower back

Exercises for Upper Back Health (Often Neglected)

• •Face pull (cable with rope): Trains the rear deltoid, external rotators, and middle/lower traps — the muscles most people neglect. Pull toward the face at upper-chest/chin height, elbows above the hands, and finish with hands beside the ears. Do these at the end of every upper body session
• •Prone Y-raise (dumbbell or cable): Lie face down and raise arms into a Y position. Trains the lower traps and is one of the best exercises for long-term shoulder health and upper back posture
• •Chest-supported reverse fly: Trains the rear deltoid in its primary function (transverse extension). Important complement to all rowing work

Programming Back Training

• •Frequency: 2x per week for most intermediate lifters. The back is large enough and recovers quickly enough for twice-weekly training
• •Volume: 14–22 sets per week. Split between vertical pulls (lat-focused) and horizontal pulls (middle back-focused)
• •Typical session structure: Start with heaviest compound pull (barbell row or weighted pull-up), follow with a second compound (cable row or dumbbell row), then isolation or variety work (face pulls, pulldowns), finish with any upper back health work
• •Log your back sessions in YourFit — tracking both vertical pull and horizontal pull volumes ensures you're not neglecting either the width or thickness aspects of back development

The Bottom Line

Back development requires both vertical pulling movements (pull-ups, lat pulldowns) for width and horizontal pulling movements (rows of all types) for thickness. Include face pulls or rear delt work for upper back health. Train back twice per week with 14–20 weekly sets, progressively overload your rows and pull-ups, and be patient — back development shows itself slowly but creates the most dramatic physique changes of any muscle group when it's fully developed.
