Straight Hand Shoulder Movement

This drill holds both arms straight out at shoulder height and moves them through slow, controlled circles and sweeps, warming the rear and side delts along with the muscles between the shoulder blades. Maddy uses it at the top of upper-body sessions and as a between-sets reset for rounded shoulders. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Muscles worked

Rear shoulders · posterior deltoid Side shoulders · medial deltoid Upper traps · upper trapezius Mid back · rhomboids

Level — Beginner

Beginner; deceptively humbling if you keep honest height and slow tempo for the full duration.

Proper form — 5 cues

Lift both arms to a T at exact shoulder height, palms facing down.
Reach long through the fingertips as if touching both walls.
Draw small, slow circles and let them grow gradually over the set.
Keep the shoulder blades sliding down away from the ears throughout.
Reverse the circle direction halfway through the time.

Breathing: Slow nasal breathing throughout — one circle per inhale, one per exhale is a good metronome.

The 3 mistakes Maddy corrects most

Letting the arms drift below shoulder height as they tire.. The burn in the delts tempts the arms downward, which quietly removes the very muscles you are warming up. Fix: Check the T in a mirror at the halfway mark, or brush the fingertips against a line on the wall to recalibrate.

Shrugging into the neck as the circles grow.. Once the upper traps take over, the small shoulder stabilisers stop doing the work and the neck stiffens. Fix: Pause, exhale, set the blades down, and restart with smaller circles.

Spinning fast little circles to pass the time.. Speed replaces muscular control with momentum, and the warm-up effect on the stabilisers disappears. Fix: Match each circle to a slow breath — the drill should feel deliberate, almost heavy, by the end.

Common questions

Are arm circles actually useful or just filler?

Done with intent, they raise local blood flow, rehearse shoulder positions you are about to load, and give the rear and side delts an isometric wake-up — which is why they survive in serious warm-ups. Done as floppy fast spins, they are filler. The difference is entirely in arm height, blade position, and speed, which is what the cues above lock down.

My arms burn after 30 seconds — is that normal?

Completely. Holding straight arms at shoulder height is an isometric for the delts, and most people have never spent continuous time there. The burn is fatigue, not damage. Break the time into two or three shorter holds and rebuild — most clients double their comfortable duration within a couple of weeks of consistent warm-ups.

Should I add small weights to shoulder circles?

Only after bodyweight circles are silky for a full minute in both directions. Even half-kilo plates dramatically increase the demand at this lever length, and loading too early just recruits the neck and traps. As a warm-up, bodyweight is usually the right dose forever; if you want loaded work at this angle, lateral raises and T-raises are better tools.
