Lie on your back on the floor with knees bent and feet planted. Hold a kettlebell in one hand at chest level, elbow bent and close to your body. Press the kettlebell upward until your arm is fully extended, keeping your wrist stacked and core engaged. Slowly lower the kettlebell back down with control until your upper arm lightly touches or nears the floor, maximizing range of motion. Pause briefly at the bottom, then press again while maintaining a stable torso and avoiding lower back arching. Repeat for all reps before switching sides.
