The double-kettlebell windmill is an advanced kettlebell exercise emphasizing core strength and shoulder and hip mobility and stability. Because it involves holding one weight overhead while holding another under the torso, it builds strength across the core and stability in the shoulders. It doesn't work well in a metcon or conditioning setting, and shouldn't be performed under intense fatigue.
Builds strength throughout the abdomen, particularly the deep core (transversus abdominus) and obliques
Gives intense strength stimulus even with relatively light weights
Builds shoulder stability, hip mobility, and thoracic spine mobility
Place a kettlebell in front of your front foot and clean and press a kettlebell overhead with your opposite arm. Clean the kettlebell to your shoulder by extending through the legs and hips as you pull the kettlebell towards your shoulders. Rotate your wrist as you do so, so that the palm faces forward.
Keeping the kettlebell locked out at all times, push your butt out in the direction of the locked out kettlebell. Turn your feet out at a forty-five degree angle from the arm with the locked out kettlebell.
Bending at the hip to one side, sticking your butt out, slowly lean until you can retrieve the kettlebell from the floor. Keep your eyes on the kettlebell that you hold over your head at all times.
Pause for a second after retrieving the kettlebell from the ground and reverse the motion back to the starting position.
