  • + Really focused on your side delts.
  • − Around 12 kg, the swing creeps in and the side delts lose tension at the bottom.

Machine Lateral Raise: pros and cons

  • + Easy to progress: add a little weight or one more rep each week.

  • + Really focused on your side delts.

Which should you pick?

  • Pick Dumbbell Lateral Raise if you've got the kit and want a move that's simple to load up week after week.
