The back and biceps work extremely well together because most pulling exercises naturally require both muscle groups at the same time.
—
☑️ The back usually produces the larger movement, while the biceps help bend the elbow and complete the pull.
☑️ Back exercises already warm up the biceps.
By the time you reach curls, your biceps have already accumulated productive training volume.
☑️ The back can handle heavier loads.
Compound pulling movements allow the biceps to contribute under loads that would be impossible during isolation curls alone.
☑️ Strong biceps can improve pulling performance.
If your elbow flexors are stronger, they are less likely to become the limiting factor during rows and pulldowns.
