The kettlebell alternating press on floor is an exercise that targets the chest. To do this exercise, you will need a kettlebell and a mat. Start by lying on your back on the mat with your knees bent and your feet flat on the floor. Hold the kettlebell in your right hand and extend your arm straight up over your chest. Slowly lower the kettlebell to your chest, then press it back up to the starting position. Repeat this movement for 10-12 repetitions, then switch arms and do the same number of repetitions with your left hand. This exercise is a great way to build strength and definition in your chest muscles.
