Curl it, press it, two moves one smooth rep.
Finish each phase before starting the next, no rushing the transition.
The biceps drive the first half of every rep, curling the dumbbells to your shoulders before the pressing phase carries them overhead and back down through the same path in reverse. Chaining the two movements keeps the arms under tension twice as long as a curl alone and turns one pair of dumbbells into a full arm-and-overhead sequence. It earns its place in time-crunched sessions and circuits where every rep needs to do double duty.
Whatever your curl can handle strictly, because the curl is the weaker half and it goes first. If you have to swing the dumbbells up to reach your shoulders, the presses that follow are built on cheated reps.
Palms turn forward at the shoulders so the press travels in its natural line overhead. Skipping the rotation forces an awkward pressing angle and usually makes the dumbbells clank around at the top.
Both, with caveats. It is brilliant for efficient full-arm work and conditioning circuits, but because the load is capped by your curl strength, dedicated pressing sessions still need their own heavier work.
