How to perform See-Saw Press (Alternating Side Press)

  1. Grab a dumbbell with each hand and stand up erect.
  2. Clean (lift) the dumbbells to the chest/shoulder level and then rotate your wrists so that your palms are facing towards you as if you were getting ready to perform an Arnold Press. This will be your starting position.
  3. Now start extending your left arm overhead as you rotate the wrist so that the palm of your hand faces forward as you go up. Your elbows should come out also as you lift the weight. Simultaneously, you will also be bending from your hip to your opposite side. Tip: If you perform the exercise correctly, is should look as if you are trying to reach for something overhead on the right hand side of your body, but with your left arm. Breathe out as you perform this movement.
  4. Once you reach the top position breathe in. Then, with the weight fully extended overhead and you bent over to your right hand side, begin the movement to the left side.
  5. Repeat for the recommended amount of repetitions.

Muscles worked

  • Shoulders (primary): raises and rotates the arms and drives everything overhead.
  • Core (secondary): braces the trunk and resists twisting to protect the spine.
  • Triceps (secondary): straightens the elbow to lock out every press and pushdown.

Sets & reps by goal

Hypertrophy3–4 × 8–12Moderate (~65–75%)60–90 s
Endurance2–3 × 15–20Lighter (~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.
  • Stop a rep or two short of failure on most sets to keep form clean and recover faster.

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.
