Lateral raises are the best exercise for lateral deltoids

A common recommendation in bodybuilding is that dumbbell lateral raises are the superior exercise for targeting the lateral (middle) head of the deltoid. While the overhead press is the primary compound movement for shoulders, lateral raises are frequently cited as essential for maximizing side delt development due to their isolation of this specific muscle head.

EMG study comparing muscle activation of the lateral deltoid during various shoulder exercises in trained men. Lateral raises produced the highest peak EMG activation in the middle deltoid compared to overhead press, upright rows, and front raises. The authors concluded that lateral raises are the most effective isolation exercise for targeting the lateral deltoid head.

EMG comparison of several shoulder exercises showed that while lateral raises produced high middle deltoid activation, behind-the-neck presses and wide-grip upright rows also produced comparable EMG readings in the lateral deltoid. The findings suggest lateral raises are effective but may not be uniquely superior to all alternatives.
