Build a back and bulletproof your core in one rep.
Don't let your hips rotate open as you row, fight the twist the whole set.
Rowing a dumbbell from a two-point stance with the opposite leg reaching back means the lats and upper back pull while the entire trunk fights the twist that the single-sided load creates. The biceps assist the row, but the real bonus is the anti-rotation work your core is doing on every rep. One side at a time, it builds a back and a bulletproof brace in the same set.
Far lighter than your regular one-arm row, because the two-point stance is the limiting factor. Pick a dumbbell you can row with zero visible twist through your hips, and treat any wobble as a signal to go lighter.
The dumbbell is pulling your whole torso toward the floor and your core is losing the argument. Squeeze the down-side glute, push the extended heel back hard, and slow the row down. If the twist persists, drop the weight.
A bench-supported row lets you move more weight, this version taxes your trunk stability at the same time as your back. It suits warm-ups, core-focused sessions and anyone who wants their rowing strength to hold up outside perfectly braced positions.
