How to do it

Set up

Stand tall or sit on a stable bench with both dumbbells at shoulder height.
Keep the palms forward and the trunk upright.

Do the rep

Press one dumbbell overhead until that elbow is straight. Keep the other dumbbell at the shoulder.
Lower to the shoulder under control, then press with the other arm.

What counts as a rep

A rep counts when one elbow straightens overhead and that dumbbell returns to the shoulder. Count both sides together and alternate arms.

Breathing

Exhale as you lift; inhale as you lower.

Cues

Keep the waiting hand at the shoulder.
Keep the legs still.
Return before you change arms.

Common mistakes

Leaning to one side
What you seeThe trunk shifts sideways as one arm presses.
FixUse less load and keep both sides of the waist long.
A steady trunk keeps the load over the base of support.

Stop the set if

Stop if you feel sharp pain.
Stop if you cannot control the dumbbell overhead or keep the torso upright.
End the set when you cannot meet the stated rep standard under control.

How this page was checked

Draft. A coach reviewer has not signed this off yet.

Draft text is original copy for Wave 2 batch 9, written from the blueprint CSV row and the owner rules approved 2026-10-12 in #340. No human review is complete.
Technique, cues, rep standard, breathing, stop cues, and error corrections need independent sources and the assigned review tier (blueprint two-source rule).
Programming roles, skill tier, failure cost, timed use, goal fit, and equipment follow the owner rules; the switch-on PR must confirm them.
Legacy relations and engine edges stay empty until the progression ladder lane and S2-CAT-005.
Timed use and goal fit copy ex_dumbbell_shoulder_press. The copied timed-use state is disallowed; no review evidence is claimed for this draft.
Rule 1 gives home yes because every required picker item is a dumbbell or bench. The CSV says home false. Environment and programming location constraints include gym and home.
Dumbbell load uses kg with load-and-reps and the allowed metrics of ex_dumbbell_shoulder_press (rule 1).
Rule 2 gives this movement primary_vertical_push + secondary_push.
Failure cost moderate: the user must control the dumbbells at the stop, as ex_dumbbell_shoulder_press (rule 3).
Skill tier beginner: a new user can perform one clean rep in the first session, as the owner ruled (rule 3).
The CSV says bilateral. The arms alternate and count both sides together, as ex_reverse_lunge; two dumbbells are required (rule 1).
Anatomy uses the CSV planning hints; the assigned review tier must confirm it.
The waiting arm stays at shoulder height. The CSV does not specify this alternating variant; coach review must confirm it.

All instruction and editorial text in this record is original draft copy written for Allena. Planning metadata comes from the internal Wave-2 blueprint CSV.
