kettlebell alternating press on floor

Start by lying on your back on the floor with your knees bent and feet flat on the ground. Hold a kettlebell in each hand, with your palms facing towards your feet and your arms extended straight up towards the ceiling. Lower one kettlebell down towards your shoulder while keeping the other kettlebell extended straight up. Press the lowered kettlebell back up to the starting position while simultaneously lowering the other kettlebell down towards your shoulder. Continue alternating the press motion with each kettlebell for the desired number of repetitions.
