How to Perform
-
1
Setup: Stand tall with dumbbells at your sides, elbows slightly bent. Use 20-40% more weight than full-range lateral raises.
-
2
Position: Keep shoulders down and back, arms in the scapular plane, wrists neutral.
-
3
Raise: Lift the dumbbells to about 45 degrees (max 60) in a slow 2-3 second concentric.
-
4
Pause: Hold for one second and squeeze the medial delts without shrugging.
-
5
Lower: Control the eccentric for 3-4 seconds, keeping constant tension.
Common Mistakes
Going Too High
Raising past 45-60 degrees shifts tension away from the weak range.
Using Light Weight
These are heavy partials. If it feels easy, add weight.
Rushing Reps
Fast reps reduce tension and increase injury risk with heavy loads.
Shrugging or Swinging
Momentum recruits traps instead of isolating the medial delts.
Training Notes
Partial Lateral Raise (Bottom Half) is safest when the ribs stay down and the shoulder blades glide naturally. Avoid excessive arching by tightening the glutes and keeping the pelvis stacked. A neutral wrist and elbows slightly in front of the body keep the press in a strong, shoulder‑friendly line.
Use a controlled lowering phase to build stability. A 2–3 second eccentric helps the delts do the work rather than the traps. If you feel pinching, reduce range slightly and keep the elbows from drifting too far behind the body.
For hypertrophy, aim for 3–4 sets of 8–15 reps, leaving 1–2 reps in reserve. For strength, keep reps lower (5–8) and focus on crisp technique. Rest 90–150 seconds for moderate loads; longer for heavier sets.
If the traps take over, lower the load and think about “shoulders down and wide.” A slightly wider grip can reduce internal rotation stress during upright‑row type patterns. For raises, stop at shoulder height to avoid unnecessary joint strain.
Pair Partial Lateral Raise (Bottom Half) with a rear‑delt or external‑rotation movement to balance the shoulder. A simple combo is a press plus face pulls or rear‑delt flyes. Over time, track reps and load while keeping the same smooth tempo.
Warm up with 1–2 lighter sets and some shoulder mobility before heavy work. Small adjustments—seat height, grip width, or range—can make a big difference in comfort and deltoid activation.
A slight scapular‑plane angle (about 30° forward of the body) is usually the most shoulder‑friendly for presses and raises. If your joint feels irritated, reduce range and keep the elbows slightly forward.
For lateral raises, think “long arms and soft elbows,” and stop when the hands reach shoulder height. Heavier weights tend to shift the work to the traps, so keep the load moderate and focus on tempo.
Balance your week with at least one rear‑delt movement and some external rotation work. This keeps the shoulder joint centered and reduces the risk of impingement over time.
Pro Tips
-
Pair After Full Range
Do these after full-range laterals to overload the weak range when delts are warm.
-
Use Straps if Needed
Grip shouldn’t be the limiting factor on heavy partials.
-
Respect the Angle
Use a mirror to learn the 45-degree stop point and keep form consistent.
-
Progress Gradually
Increase load by small increments every few weeks for safe strength gains.
Variations
Partial Cable Lateral Raise
Constant tension through the bottom half.
Seated Partial Lateral Raise
Removes body English and enforces strict control.
Bottom-Half Machine Lateral Raise
Machine-supported partials for stability.
Tempo Partials
Use slower eccentrics for more time under tension.

Tip of the Day PRO
Keep the movement strict and slow. The bottom half is weak, so control beats momentum every time.
