Dumbbell Lying Supine Biceps Curl
Curling while lying flat on your back changes the resistance curve compared to a standing curl, since gravity pulls the dumbbell in a different direction relative to the torso. That flat position also removes any ability to swing the hips or lean back for momentum, one of the easiest ways standing curls get cheated. It's a strict, floor-based alternative when a preacher bench isn't available.
