Quick answer: EMG research consistently shows straight-arm lateral raises activate the medial deltoid more than bent-arm versions during a single measured set. But a separate, important body of research questions whether higher EMG activation during one set actually predicts more…
Quick answer: Population-level research (EMG studies, activation data) can tell you general tendencies, but a growing body of research on individual variability shows people respond quite differently to the same training stimulus. Rather than treating “bent vs. straight” as a…
Quick answer: Research directly comparing shoulder press and lateral raise EMG activation found both exercises produce meaningfully high medial deltoid activation — close enough that some lifters question whether dedicated lateral raise work is really needed if they’re already pressing…
Many lifters grind through set after set, only to see minimal progress. But here’s the kicker: the problem might not be your effort, it’s your form.
