Row
Single-arm dumbbell row
Works
Also works
Equipment
Unilateral (one side at a time)
How to do it
- Place one knee and the same-side hand on a flat bench.
- Grip the dumbbell with your other hand and let your arm hang extended.
- Keep your back neutral and nearly parallel to the floor.
- Pull the dumbbell toward your hip by driving your elbow back.
- Lower the dumbbell under control until your arm extends.
- Complete all reps on one side, then switch.
Common mistakes
- Rotating the torso to lift more weight
- Pulling with the biceps instead of the back
- Shrugging the shoulder toward the ear while pulling
What the evidence says
If your lower back is the limiting factor, the variation matters: comparing the inverted row, the standing bent-over row and the one-arm cable row, the inverted row produced the highest latissimus dorsi activation with the lowest lumbar spine load, while the standing bent-over row imposed the largest spine load.

At matched effort, free-weight rows demand more from the erector spinae than machine rows, and the unilateral version activates the external oblique more than the bilateral one. Pick a machine or chest-supported row when you want your upper back to be the limit, not your lower back.

Rows do grow the biceps, but they don't replace curls: over 8 weeks training one arm with the dumbbell row and the other with the biceps curl, elbow flexors grew 11.1% with the curl versus 5.2% with the row.

What isn't settled: No trial has yet compared row variations by measuring how much the back actually grows: what exists is muscle activation and spine load measured in a single session, and activation doesn't predict hypertrophy. Choosing between barbell, Pendlay, T-bar or Meadows rows is, for now, a matter of comfort and of what fails first — not of evidence.
