Drag the weights up your body for a brutal biceps squeeze.
Keep the dumbbells glued to your body, your elbows go back not forward.
Dragging the dumbbells up your torso with elbows travelling back already keeps the biceps under tension where regular curls go soft, and the added pause at the top turns that peak position into a held contraction. Every second of the pause is pure biceps, since the path leaves no room for shoulder swing or momentum. It is a hypertrophy tool for lifters who want more from moderate dumbbells.
A genuine one-second squeeze, counted honestly. If the pause disappears as the set gets hard, the weight is too heavy for the variation, and shrinking the pause quietly turns it back into a regular drag curl.
Just the pause, but it changes the maths. The held squeeze at the top adds time under tension exactly where the drag path keeps the biceps loaded, so the same dumbbells produce noticeably harder sets.
Deep in the biceps, especially at the top of each rep during the pause. If your shoulders or traps are lighting up instead, the dumbbells have drifted away from your body and the elbows have stopped travelling back.
