Two kettlebells, alternating pulls, no rest between sides.
Keep your hips locked in the hinge, do not let your torso rock as you alternate.
Holding the hinge with a bell in each hand, you row one side at a time while the other arm hangs loaded, which means your back never fully unloads and your torso has to fight rotation on every pull. The lats and mid-back drive each elbow to the hip with the biceps assisting, while the alternating pattern doubles as an anti-rotation drill for the trunk. It earns its place as the rowing variation that trains each side independently without ever letting you rest in the hinge.
Alternating forces your core to resist the twist as one side pulls and the other hangs, and it exposes any difference between arms. Rowing both together is a fine strength option, but the alternating version buys extra trunk work for free.
Your hinge is probably too deep or too soft for your current strength. Raise your torso angle slightly, brace harder before the set, and keep the bells over mid-foot. If it persists, build hinge endurance with lighter bells first.
As a rule, yes, since the hanging bell counterweights the rowing side. Deliberately mismatching loads is an advanced trick for hammering a weak side, but start matched and let strict reps reveal whether a gap even exists.
