In this video Carolina is demonstrating how to properly activate your glutes while also increasing range of motion in the shoulders. Use this as an exercise in the gym or prior to teeing off to help get your body ready to swing.
Keep your glutes contracted throughout the entire movement, while also keeping your abdominals tight to keep your back from arching. While bringing the club overhead, only go as far as you feel comfortable. Your range of motion will improve with time and practice.
