http://AskTheTrainer.com/medicine-ball-workouts.html Personal Trainer Michael Behnken, MS, NASM-CPT-PES, CSCS Medicine ball push-ups are a fabulous triceps exercise. If you have strong triceps you can perform these as a finisher. If your triceps are not the strongest body part, do these at the beginning of your workout or you won't be able to do many. The key is proper form. You must lower your chest all the way down to the medicine ball. To keep the focus on your triceps to the maximum you should keep your elbows in towards your sides. Keep your head up and lower your whole body at the same time. If you can't perform exercises properly it is probably best to pick an easier exercise. http://AskTheTrainer.com/medicine-ball-workouts.html
