A slow, controlled arm circle performed with light weights that trains all three deltoid heads and the rotator cuff through a continuous range, useful for shoulder endurance and warm-up work.

Pattern
Arm circumduction
Setup
01Hold a light dumbbell in each hand at the sides.
02Stand with feet hip width apart and a braced, upright torso.
03Keep the arms nearly straight with a soft elbow bend.
04Set the shoulder blades down away from the ears before the first circle.
Execution
01Raise the arms out and sweep them in a slow, full circle: forward, up, back, and down.
02Keep the circle diameter as large as pain-free mobility allows.
03Complete the planned reps in one direction, then reverse the circle.
04Maintain an even tempo of roughly 3 to 4 seconds per full circle.
Checkpoints
-Circles stay smooth and round, not segmented flicks.
-Torso stays still; no rocking to help the arms around.
-Both directions get equal work.
-Traps stay quiet as the arms pass overhead.
Common mistakes
-Using dumbbells heavy enough to shrink the circle into a small wobble.
-Speeding up and letting momentum carry the weights.
-Shrugging hard as the arms pass the top of the circle.
-Skipping the reverse direction.
Programming notes
-Use 2 to 3 sets of 8 to 12 circles per direction with 1 to 4 kg per hand.
-Works well as a warm-up before pressing or as a high-rep finisher for the delts.
-Progress with more reps or slower tempo before adding weight.
