How to do it

  1. Stand in chest-deep water with your feet hip-width apart, one slightly ahead of the other.
  2. Hold the aquatic dumbbells just in front of your chest, fully underwater, with your palms facing down.
  3. Position your elbows below shoulder height, angled slightly away from your sides.
  4. Press the dumbbells straight forward beneath the surface until your arms are nearly straight.
  5. Draw the dumbbells back to the starting position at a steady pace.

Form cues

  • Keep your wrists straight.
  • Keep your ribs over your hips.
  • Exhale as you press.

Common mistakes

  • Shrugging toward your earsKeep your shoulders relaxed away from your ears throughout the movement.
  • Rocking to move the dumbbellsKeep your torso still so the movement comes from your arms rather than your body weight.
  • Snapping your elbows straightSlow the final part of the press to avoid a hard elbow lockout.

Safety

Buoyant dumbbells pull upward and can strain your shoulders if they rise unexpectedly, especially when you are tired. Water resistance can also disturb your balance on a slippery pool floor.

  • Use a supervised pool area with secure footing near an accessible edge.
  • Start with smaller foam dumbbells before increasing their size or your pressing speed.
  • End the set if you cannot control the upward pull.
  • Move to the pool edge if your footing becomes unstable.

If shoulder pain or balance problems limit your control, use a smaller range of motion or ask a physiotherapist about an appropriate alternative.
