Stand holding a kettlebell between your legs and take a stance that is wider than hip width with your toes slightly turned out. Bend your knees and drive your hips back but don't allow them to go lower than your knees. Brace your core, keep your chest up and keep a neutral spine. Shoulders should stay back and traps should stay relaxed, with your arms fully extended gripping the kettlebell. This is the start position. Imagine then pushing the ground away from you with your feet and as you do so driving your hips forward and extending at the knees. All the while exhaling as you do so. As you reach full hip extension pull the kettlebell up to directly under your chin. Allow your grip to shift slightly, coming to the sides of the kettlebell handle. Maintaining the kettlebell at chest height, bend at the knees and drive your hips back and down. Lower until your thighs are parallel to the floor or deeper depending on your range, making sure your knees are pointing in the same direction as your feet. Then extend the knees and hips to drive yourself back up to create momentum. Drive the kettlebell straight up overhead. Pause at the top and then return to the start position and perform the sequence again. Repeat for the required number of reps (or time).
