Technique.

  • Pick up two dumbbells and push your butt backwards so that your body is tilted forwards at around 45 degrees.
  • Lift the dumbbells out to the sides, keeping a slight bend in your elbows, until your arms are parallel with the floor. From the top position, slowly lower the dumbbells back down to the starting position.
  • Avoid using momentum to swing the dumbbells up. Keep your back at the same angle throughout the exercise maintaining a neutral spine (do not arch your back).
