Well, there could be a reason for this. Maybe you aren’t training the muscle in the most efficient way and thus hit more of your front shoulder.⁣ Best would be to keep your arm in the „scapular plane“, thus you ensure to perfectly recruit the muscle fibres of your side delts.⁣ Lateral raises are a great exercise to build shoulder strength and mobility, but the form can be tough but worth it! ~ Berceste
