The Kroc row, named after powerlifter Matt Kroczaleski, is a one-arm dumbbell row taken to extreme volume and weight — typically 20-30 reps with the heaviest dumbbell you can grip. Body english is allowed (encouraged, even), making it one of the most aggressive grip and back builders in the gym.
What it is
The Kroc row is a heavy, high-rep dumbbell row with allowed body english. The lifter grabs a heavy dumbbell — often heavier than they could lift with strict form — and rows it for 20-30 reps with controlled momentum from the hips and torso. It builds the lats, traps, forearms and grip simultaneously, and serves as a brutal capacity-builder for deadlift assistance.

How to Kroc row: 5 steps
-
Set up with heavy dumbbell
Grab the **heaviest dumbbell you can grip for 20+ reps.** Other hand braced on a bench.
-
Hinge over
**Hinge to about 45°, flat back, knees slightly bent.** Dumbbell hangs at full extension.
-
Initial strict reps
**Pull strictly for the first 10-15 reps,** elbow tight to body, lat squeeze at top.
-
Allow body english
**As fatigue accumulates, allow controlled hip and torso drive** to keep moving the dumbbell.
-
Push to 20-30 reps
**Continue until 20-30 total reps.** Grip giving out is the cue to stop. Switch sides.
How it differs from dumbbell row
- Heavier weight than strict form allows. Often the heaviest dumbbell in the rack.
- Body english allowed. Controlled torso swing helps move the load — not cheating, but technique-aware.
- High-rep, high-volume. 20-30 reps per side is the standard, sometimes much more.
- Massive grip work. Long sets with heavy dumbbells build forearm strength fast.
Common mistakes
When to use this variation
Use Kroc rows as a deadlift accessory, grip builder, or upper-back capacity finisher. Program 1-2 sets of 20-30 reps per side, working with the heaviest dumbbell you can hold for that duration. Once you can do 30 reps comfortably, jump to the next dumbbell size. Best programmed once a week — the volume and grip work tax recovery.
FAQ
Is it really not cheating?
It allows body english intentionally as part of the technique. Used in the right context (capacity work, accessory), it is a legitimate tool. Not for pure strict-form hypertrophy training.
Straps or no straps?
Both protocols exist. No-strap Krocs maximise grip work. Strap-on Krocs let you hit much higher weights for back capacity. Many lifters do both.
How heavy?
Start with a dumbbell you could do 12-15 strict reps with. Push it to 20-25 reps with body english. As reps come, jump up in dumbbell size.
