How to perform Power Partials
- Stand up with your torso upright and a dumbbell on each hand being held at arms length. The elbows should be close to the torso.
- The palms of the hands should be facing your torso. Your feet should be about shoulder width apart. This will be your starting position.
- Keeping your arms straight and the torso stationary, lift the weights out to your sides until they are about shoulder level height while exhaling.
- Feel the contraction for a second and begin to lower the weights back down to the starting position while inhaling. Tip: Keep the palms facing down with the little finger slightly higher while lifting and lowering the weights as it will concentrate the stress on your shoulders mainly.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Shoulders (primary): raises and rotates the arms and drives everything overhead.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
