준비 자세
- 01Hold a light dumbbell in each hand and hinge at the hips until the torso is near parallel to the floor.
- 02Keep a flat back with knees softly bent.
- 03Let the arms hang straight down with palms facing each other.
- 04Set a slight bend in the elbows and hold it for the whole set.
수행
- 01Raise the dumbbells out to the sides in a wide arc.
- 02Lead with the elbows until the upper arms are roughly level with the torso.
- 03Pause briefly at the top without squeezing the shoulder blades hard together.
- 04Lower slowly back under the shoulders without swinging.
체크포인트
- -Torso angle stays fixed; no bouncing upright to lift the weight.
- -The arc goes out to the sides, not back toward the hips.
- -Elbow bend stays constant instead of pressing the weight up.
- -Neck stays neutral, eyes down at the floor.
흔한 실수
- -Using dumbbells that are too heavy and swinging with the torso.
- -Turning the fly into a row by bending the elbows more as the set goes on.
- -Shrugging the traps at the top of each rep.
- -Standing too upright so the front delts take over.
프로그래밍 노트
- -Use 3 to 4 sets of 12 to 20 reps with strict control.
- -Program 2 or more weekly sessions to offset heavy pressing volume.
- -Chest-supported on an incline bench is a good option if the lower back fatigues.
