公司描述
To do medial deltoid action, perform lateral raises. Stand with feet shoulder-width apart, hold dumbbells in each hand by your sides. Keep a slight bend in your elbows and lift the weights out to your sides until your arms are parallel to the ground. Hold for a moment, then lower them back down slowly. Focus on engaging the medial deltoid during the lifting and lowering phases. Aim for 10-12 repetitions to effectively work the medial deltoid.
