Stand with feet about shoulder-width apart holding a kettlebell in one hand at the rack position (resting at shoulder height). Begin by performing a squat—push your hips back and bend your knees until your thighs are at least parallel to the floor while keeping your chest upright. Drive powerfully through your heels to stand up. As you reach full extension, use the momentum from your legs to press the kettlebell overhead in one continuous motion. Lock your arm out overhead, then bring the kettlebell back down to the rack position under control. Repeat for reps before switching sides.
