Sandbag One Arm Row
The upper back drives this single-arm sandbag row, the shifting filler forcing a tighter grip and harder bracing than a clean dumbbell.
Level: Foundation
Primary: Back - Upper
Secondary: Back - Lower Biceps Shoulders - Rear
Movement: Compound
Tags: Pull Unilateral
Type: Strength (Weight Lifting)
Equipment: Sandbag
Target muscles
The latissimus dorsi, rhomboids and mid-trapezius pull the bag to the ribs, with the rear deltoids and biceps assisting at the top of the row. Because a sandbag has no balanced handle, the forearm flexors grip far harder to keep the load from rolling, and the lower back and obliques work isometrically to resist the rotation the offside weight tries to create. The free hand braces on a knee or bench so the working side can move through a full range without the trunk twisting.
How to perform
Setup
Stand in a short stride, hinge forward to about 45 degrees and plant your non-working hand on the same-side knee or a bench. Grip the bag by a handle or scoop it from the floor so it hangs straight down under your shoulder. Set a flat back, ribs down, and brace the trunk before the first pull.
Execution
Drive the elbow up and back, leading with the elbow rather than the hand, and pull the bag toward your lower ribs until your shoulder blade is fully retracted. Squeeze the lat and mid-back hard at the top, then lower under control until the arm is long and the shoulder blade reaches forward. Keep the hips square the whole time — the bag wants to drag your torso open, so resist that rotation actively. Finish every rep on one side before switching.
Common mistakes
- Letting the torso rotate open with each pull, which trades back work for momentum and stresses the spine.
- Yanking with the biceps and shrugging the trap instead of driving the elbow and retracting the shoulder blade.
- Rounding the lower back at the bottom rather than keeping a flat, braced spine.
- Letting the bag swing forward and using the rebound to start the next rep.
Progressions and regressions
Regress to a supported dumbbell row or a bench-supported sandbag row so the chest is propped and the lower back is spared. Progress by adding filler to the bag, slowing the lowering phase to three seconds, or pausing for a count with the bag pinned to the ribs. A bear-hug sandbag row or an inverted row off a fixed bag scales the demand differently when you want variety.
Programming notes
Program it as a back-builder or accessory pull, 3-4 sets of 8-12 per arm, balanced left and right. The heavy grip and anti-rotation cost make it a strong unilateral complement to a bilateral barbell or sandbag deadlift. Keep the reps honest — when the torso starts swinging to move the bag, the set is done. It fits well on a pull day or as the rowing component of a full-body session.
