    • Barbell
    How to perform it
    1. This drill teaches the delivery of the barbell to the rack position on the shoulders. Begin holding a bar in the scarecrow position, with the upper arms parallel to the floor, and the forearms hanging down. Use a hook grip, with your fingers wrapped over your thumbs.
    2. Begin by rotating the elbows around the bar, delivering the bar to the shoulders. As your elbows come forward, relax your grip. The shoulders should be protracted, providing a shelf for the bar, which should lightly contact the throat.
    3. It is important that the bar stay close to the body at all times, as with a heavier load any distance will result in an unwanted collision. As the movement becomes smoother, speed and load can be increased before progressing further.

    Sets and reps: 3 or 4 sets of 6 to 10 reps.

    • Primary muscle: delts, the same as the Weighted Round Arm

How to Choose the Right Weighted Round Arm Substitute

Pick a substitute based on which deltoid head you want to bias, available equipment, and joint tolerance. For medial/lateral emphasis choose lateral raises with thumb slightly up to increase abduction torque; for anterior focus use incline front raises with a straight path. Consider the exercise plane and moment arm: cables maintain load through the whole arc while dumbbells stress a peak position. If you have shoulder issues, select low-load, high-tempo reps and prioritize scapular stability, keep the ribs down and avoid shrugging.

Weighted Round Arm FAQ

What muscles does Weighted Round Arm work?

Weighted Round Arm primarily targets the lateral deltoid with secondary activation of the anterior deltoid and upper trapezius. It stresses shoulder abduction mechanics, so stabilizers like the rotator cuff and scapular retractors fire to control the humeral head.
