Machine shoulder press

The machine shoulder press is the easiest way to overload the delts without negotiating the stability demands of a barbell press. For most lifters past 40, it should be the main shoulder lift.

Setup

Sit in the machine with the back fully against the pad. Adjust the seat so the handles sit just below shoulder height when your arms are bent. Feet flat on the floor, trunk braced before the first rep.

How to do it

  1. 1

    Set the height

    Most machines have four to six seat positions. Pick the one that puts the handles at chin level when your hands grip them. Too high and the shoulder gets pinched at the top; too low and the chest takes over.

  2. 2

    Press up

    Drive the handles up in a smooth, even arc. Both arms should reach the top at the same moment. Stop just short of lockout so the joints are not the thing holding the weight.

  3. 3

    Control the descent

    Lower over three seconds. The handles return to chin height; the elbows finish slightly forward of the shoulders.

  4. 4

    Reset and repeat

    No bouncing at the bottom. Take a breath, brace again, drive the next rep.

Common mistakes

  • • Arching the lower back to drive the weight up, which turns the lift into a poor incline bench.
  • • Locking the elbows hard at the top, where the load shifts onto the joint.
  • • Pressing with the elbows flared straight out to the side, which loads the rotator cuff.
  • • Lifting too fast and bouncing at the bottom.
  • • Sitting too low, so the handles start above the shoulders and the joint gets pinched.

Variations

Dumbbell shoulder press

Same target muscles, free weights, both shoulders working independently. Surface and fix the side-to-side imbalance.

Standing barbell overhead press

Heavier load potential, far higher core demand. Reserve for lifters with healthy shoulders and a strong overhead position.

Landmine press

Bar locked at one end, pressed in an arc rather than straight overhead. Often the most pain-free option for older shoulders.

FAQ

How heavy should I go? +
Pick a load that allows 8 to 12 strict reps for three sets. The machine shoulder press is a strength builder, not a max-effort lift; once 12 reps feels easy, add the smallest plate available.
Why does my neck get sore? +
You are jutting the chin forward at the top of every rep. Pull the head back into the pad and keep it there. The chin stays tucked, the eyes stay forward.
Should I lock out at the top? +
Stop just short. The last few degrees of elbow extension shift the load off the muscle and onto the joint. The shoulders work harder if you stay one or two centimetres shy of full lockout.
Is this enough shoulder work on its own? +
For the front delts, yes. For complete shoulder development you also need lateral raises and rear-delt work. Two sessions a week with one press and two side or rear isolation lifts is plenty.
