You're asking how many times a week should I do barbell rows because what you're doing now isn't working. The real answer is twice, but only if you split it into one heavy day and one light day-this is the key almost everyone misses. You've probably been told to blast your back once a week on a dedicated "back day," leaving you sore for three days and seeing minimal growth. Or maybe you tried doing heavy rows three times a week and now your lower back feels permanently tight and you're exhausted. Both approaches are wrong for 90% of people trying to build a thicker, stronger back.
Training a muscle group only once a week is a huge missed opportunity. Your muscles recover and are ready for more stimulus after about 48-72 hours. By waiting a full seven days, you're leaving 4-5 days of potential growth on the table. On the other hand, the barbell row is a demanding, full-body movement that heavily taxes your central nervous system and lower back. Hammering it with heavy weight multiple times per week is a fast track to burnout, stalled progress, and injury. The solution is to train it twice: once heavy to build raw strength, and once light to accumulate volume and drive muscle growth. This gives you the frequency you need for growth without the fatigue that kills your progress.
That brutal, once-a-week back day you're so proud of is likely doing more harm than good. It's built on an outdated bodybuilding model that ignores how muscle growth actually works. The process that builds muscle, called Muscle Protein Synthesis (MPS), is elevated for about 24-48 hours after a workout. If you only train your back on Monday, by Wednesday afternoon, the growth signal is gone. You then spend Thursday, Friday, Saturday, and Sunday in a no-growth zone for your back. You're only stimulating growth for two days out of seven. That's a 28% utilization rate. It’s like wanting to get a tan but only going outside on Mondays.
The other problem is “junk volume.” After about 4-6 hard, heavy sets of an exercise like barbell rows, the return on investment plummets. Each additional set adds significantly more fatigue than it does muscle-building stimulus. So, those 7th, 8th, and 9th sets in your marathon back session aren't building you up; they're just breaking you down, creating massive fatigue that compromises your next workout. Let's look at the math:
You end up with slightly less total volume, but it's higher quality volume distributed for maximum growth and minimal breakdown. You get two chances to grow instead of one.
Stop guessing and follow a plan. This protocol removes the guesswork and is designed for consistent, measurable progress. It's built around one heavy day to drive strength and one lighter day to drive size. Separate these two workouts by at least 48 hours. A Monday/Thursday or Tuesday/Friday split works perfectly.
Before you start, you need an honest baseline. Your 5-Rep Max is the heaviest weight you can row for 5 complete reps with perfect form. To find it safely, warm up with the empty 45 lb bar. Then, add 10-20 lbs per set, performing 5 reps and resting 2-3 minutes between attempts. Your form should not break down. The moment your hips shoot up or you have to jerk the weight, you've gone too far. The last successful set of 5 is your 5RM. For an average male, this might be between 115-155 lbs. For an average female, it might be 65-95 lbs. Let's use 135 lbs as our working example.
With your 5RM established, your week is now planned. You are no longer just "doing rows"; you are executing a specific stimulus on each day.
You don't get stronger by accident. You get stronger by having a plan to add weight or reps systematically.
This is the most common complaint with barbell rows, and it's almost always a form or load issue. First, check your form. Your back must remain flat, like a tabletop. Brace your core as if you're about to be punched in the stomach. If you have to raise your torso more than 45 degrees or jerk the weight with your hips, the weight is too heavy. Drop it by 20% and perfect the movement. If your form is perfect and you still feel pain, swap barbell rows for a chest-supported T-bar row or a Pendlay row (where the bar rests on the floor between reps) for 4 weeks. These variations remove the strain from your lower back while still allowing you to train the upper back hard.
If you're coming from a background of annihilating your back once a week, this program will feel strange at first. You won't be cripplingly sore, and the workouts are shorter. This is by design. We are managing fatigue to prioritize recovery, which is where you actually build muscle. Here’s a realistic timeline of what to expect.
There is no single "best" rep range. Low reps (4-6) are superior for building maximal strength, while moderate-to-high reps (8-15) are better for stimulating muscle growth (hypertrophy). An effective program uses both. Our 2-day protocol implements this perfectly, with a heavy day for strength and a light day for size.
The barbell row is king for building overall mass and strength because you can load it with more weight. The dumbbell row is a fantastic accessory lift that allows for a greater range of motion and helps correct strength imbalances between your left and right side. Use barbell rows as your primary back-builder and single-arm dumbbell rows to supplement them.
In a standard barbell row, you maintain tension on the back muscles throughout the set. In a Pendlay row, the barbell comes to a dead stop on the floor after every single rep. This builds explosive power from a dead stop and is much safer for the lower back, as it removes the need to support the weight between reps. If you have a history of lower back pain, use the Pendlay row.
If you have never done a barbell row before, start with just the empty 45 lb Olympic bar. Your only goal for the first 2-3 sessions is perfect form. Once you can perform 3 sets of 8-10 reps with a flat back and a controlled motion, you can begin adding 5 lbs per workout. Master the movement before you add weight.
Brace your core like you are about to take a punch. Keep your chest up and your back flat. Pull the bar towards your stomach or belly button, not your chest, as this engages the lats more effectively and reduces stress on the lumbar spine. If you find yourself using momentum or jerking the weight, it is too heavy. Lower the weight immediately.
