4. 04Keep the forearms pinned to the thighs throughout.

수행

1. 01Open the fingers and let the dumbbell roll down toward the fingertips.

4. 04Finish by closing the hand fully around the handle and squeezing.

체크포인트

• -Only the fingers and hand move; the forearm stays on the thigh.
• -The dumbbell rolls under control, never slipping freely.
• -The squeeze at the top is deliberate, not a bounce.
• -The wrist stays roughly neutral rather than curling.

흔한 실수

• -Letting the dumbbell drop too far and losing it.
• -Turning it into a wrist curl by flexing the wrist.
• -Rushing reps and skipping the full finger extension.
• -Loading so heavy the range shrinks to a twitch.
