Low Lateral Chop
Stand with feet wider than hip- width, holding a single dumbbell with both hands at one end at chest height, elbows bent, to start. Squat, pivot on right foot to rotate left and extend arms out to left at shoulder height. Remaining low throughout, pivot on left foot as you rotate toward right, powerfully drawing weight across body and out to right. Continue, quickly alternating sides, for 30 seconds.
