"Dumbbell Swings" is a video demonstrating a dynamic exercise that involves swinging a dumbbell between the legs and up to shoulder height in a controlled motion. This exercise primarily targets the posterior chain muscles, including the glutes, hamstrings, and lower back, while also engaging the core and shoulders for stability. The video typically emphasizes proper form, technique, variations, and the benefits of incorporating dumbbell swings into a strength training or full-body workout routine to improve hip power, explosiveness, and overall muscle coordination.
