Lie on your back on the floor with knees bent and feet flat. Hold a kettlebell in each hand at chest level with elbows resting on the ground. Keep your core engaged and wrists neutral. Press the kettlebells upward until your arms are fully extended above your chest. Pause briefly at the top, then slowly lower them back down until your upper arms touch the floor. Maintain control throughout and avoid letting your lower back arch.
