Setup
- Stand with feet shoulder-width apart, holding a pair of dumbbells at your sides with a neutral grip (palms facing in).
- Engage your core, pull your shoulders back and down, and maintain a slight bend in your knees for stability.
- Keep a slight, fixed bend in your elbows throughout the entire movement sequence.
How to do it
- Lift one dumbbell directly in front of you to shoulder height (Front Raise), then lower it slowly; repeat with the opposite arm.
- Lift one dumbbell out to your side until it reaches shoulder height (Lateral Raise), then lower it slowly; repeat with the opposite arm.
- Hinge forward 45 degrees at the hips and lift one dumbbell out to the side (Rear Delt Fly), then lower it; repeat with the opposite arm.
- Exhale on every lift and inhale on every descent, maintaining a controlled 2-second eccentric (lowering) phase.
Form checklist
- Keep the torso stationary; do not use momentum or rock your body to lift the weights.
- Stop all raises at shoulder height to keep the tension on the deltoids rather than the joints.
- Avoid shrugging the shoulders toward the ears; keep the traps depressed.
- Lead with the elbows during the lateral and rear delt portions of the complex.
Pro tips
- Focus on a 'pouring' motion at the top of the lateral raise, slightly tilting the thumb downward to better isolate the lateral deltoid.
- Maintain a slight pause at the peak of each contraction to maximize mind-muscle connection and fiber recruitment.
Make it harder
- Perform the entire 3-move sequence (Front, Lateral, Rear) on one arm before switching to the other to increase local muscular fatigue.
- Increase the eccentric phase to 4 seconds on every rep to maximize metabolic stress.
