8 Best Back Exercises for Width and Thickness
A wide, thick back is the foundation of an athletic physique. Learn which exercises best build lat width and mid-back thickness, and how to program back training for maximum results.
Why the Back Is the Most Important Muscle Group
The best back exercises are pull-ups and lat pulldowns for width, and barbell rows, cable rows and T-bar rows for thickness. Train both movement patterns twice a week and your back will grow in every direction.
The back is the largest muscle group of the upper body and the foundation of every athletic physique. A wide back creates the V-taper that visually shrinks your waist and projects strength. But the back is not just aesthetics - a strong back stabilizes the spine, improves posture, increases your strength in every other lift and reduces the risk of lower back injuries.
The problem is that most people neglect their back because they cannot see it in the mirror. The "mirror muscles" - chest, shoulders, biceps - get all the attention, while the back gets a few half-hearted sets of lat pulldowns at the end of a workout. The result: an imbalance that leads to poor posture, rounded shoulders and a higher risk of shoulder injuries during pressing exercises.
Back Anatomy: Width vs Thickness
The Width Muscles
Latissimus dorsi (lats): the largest back muscle, running from your armpit down to your lower back. It is responsible for the V-taper and the "wings" you see on bodybuilders. It is activated primarily by pulling in the vertical plane (pull-ups, lat pulldowns).
The Thickness Muscles
Trapezius (middle and lower): provides thickness between the shoulder blades. Rhomboids: pull the shoulder blades toward the spine. Erector spinae: the muscles along the spine that create the "Christmas tree" look on a well-developed back. All of them are activated primarily by horizontal pulling (rows).
The 8 Best Back Exercises
For Width
1. Pull-Ups
Pull-ups are the king of lat exercises. Nothing activates the latissimus better than pulling your own body weight up to a bar. Use a shoulder-width or slightly wider grip, reach a full hang at the bottom, and pull until your chin clears the bar. If you cannot do pull-ups yet, start with band-assisted pull-ups or negatives (jump up and lower yourself slowly over 3-5 seconds).
2. Lat Pulldown
The lat pulldown is the machine version of the pull-up and gives you precise control over the load. It is excellent for people who cannot yet do enough pull-ups for adequate volume, and for focused work on the lat contraction. Pull the bar to your upper chest, not behind your head - behind-the-neck pulling stresses the shoulders with no extra benefit for the lats.
3. One-Arm Dumbbell Row
The one-arm dumbbell row offers a fantastic range of motion and lets you focus on each side separately. Brace one hand and knee on a bench, pull the dumbbell toward your hip (not your shoulder), and squeeze the shoulder blade at the top. This exercise builds width and thickness at the same time.
For Thickness
4. Barbell Row
The barbell row is the heaviest and most effective exercise for back thickness. Use a shoulder-width overhand grip, hinge your torso 45-60 degrees forward, and pull the bar toward your lower ribcage. Control the eccentric - do not let the bar drop. This lift demands a strong core and lower back, so use a belt for heavier sets.
5. Seated Cable Row
The cable row provides constant tension through the entire movement, which is ideal for building a mind-muscle connection with the mid-back. Use a narrow grip to focus on the middle of the back or a wide grip to emphasize the rear delts and rhomboids. At the top of each rep, imagine trying to pinch a coin between your shoulder blades.
6. T-Bar Row
The T-bar row allows heavy loading with less stress on the lower back than the barbell row. The pulling angle targets the mid-back and lower traps extremely effectively. If your gym has no T-bar platform, you can use a landmine attachment with an Olympic bar.
For Completeness
7. Face Pulls
Face pulls are essential for shoulder health and for developing the rear delts and upper traps. Use ropes on a cable machine set at face height, pull toward your face and split the ropes apart at the end of the movement. Do 15-20 reps - this is a volume and health exercise, not a max-strength lift. They pair perfectly with the pressing work in our guide to the best shoulder exercises for bigger delts.
8. Rack Pulls or Trap Bar Shrugs
For the upper traps (the muscle visible between your neck and shoulders), rack pulls from a high pin position or trap bar shrugs are the most effective options. The upper traps respond well to heavy loads and moderate reps (8-12).
Programming Your Back Training
Optimal Volume
The back can handle more volume than most muscle groups because it consists of several separate muscles. Aim for 14-22 working sets for the back per week, split across 2 sessions, with an even balance of vertical and horizontal pulling. If you want the full logic behind those numbers, read our guide on how many sets and reps to build muscle.
Sample Back Workout
- Weighted pull-ups: 4 x 6-8
- Barbell row: 4 x 8-10
- One-arm dumbbell row: 3 x 10-12
- Cable row (narrow grip): 3 x 12-15
- Face pulls: 3 x 15-20
A Simple Two-Day Split
If you train back twice a week, give each session a different emphasis:
- Day 1 (width focus): weighted pull-ups, lat pulldown, one-arm dumbbell row, face pulls
- Day 2 (thickness focus): barbell row, T-bar row, seated cable row, rack pulls or shrugs
Keep 2-3 reps in reserve on most sets, and progress by adding a rep or a small plate whenever every set of an exercise hits the top of its rep range.
Track every set and rep in the Trainera.fit workout logger. The back often progresses more slowly than the chest or arms, but when you look at the data week over week, you will see progress that would otherwise slip past you. Your coach on Trainera.fit can adjust volume and intensity based on your logs - adding sets where you stagnate and pulling back where recovery is the problem.
The Most Common Back Training Mistakes
1. Using Too Much Biceps
The most common mistake: pulling with your arms instead of your back. Think of your hands as nothing but hooks - drive your elbows toward your body rather than pulling your hands to your chest. If your biceps always give out before your back does, use lifting straps to remove grip as the limiting factor.
2. Too Much Vertical, Not Enough Horizontal Pulling
Lat pulldowns and pull-ups alone build width but not thickness. You need an equal amount of horizontal pulling (barbell rows, cable rows, T-bar rows) for a complete back. The ideal ratio: 50% vertical, 50% horizontal pulling.
3. Rounding the Back on Rows
Rounding the upper back during barbell rows shifts the load from the target muscles onto the spine. Keep a neutral spine through the entire movement, even if it means using less weight.
Build the Back You Deserve
A strong, wide back is not built in a month - it is the product of months of consistent, progressive training. But with the right program and proper tracking, progress is guaranteed. On Trainera.fit, your coach can build a back program tailored to your weak points and follow your progress through detailed performance analytics.
Every pull-up, every row, every set - all of it gets logged and analyzed. When you know exactly how far you have come month over month, motivation never runs dry.
