    Key Cues

    • Elbows stay fixed: no flaring

    • Lower to forehead, not behind head

    • Full extension at the top

    • Control the descent: 2-3 seconds

    • Keep upper arms perpendicular

    Common Mistakes

    • Elbows flaring out to the sides

    • Lowering bar behind head

    • Using shoulders to help

    • Too much weight causing form breakdown

    • Not reaching full extension

    Programming

    3-4 sets of 8-12 reps. Use an EZ-bar if straight bar causes wrist discomfort. Great after close-grip bench or dips.

    Focus on the stretch and squeeze.
