http://AskTheTrainer.com Personal Trainer Michael Behnken, MS, CSCS Pushups on the foam roller are slightly more difficult than push-ups on the floor. Some people find pushups on the roll to be easier on the wrists. When you perform this or any push-up make sure your hips and spine and head all push up in line and your chest touches the floor or foam roll in this case. Push-ups for beginners can be an only exercise but for advanced can be a finisher. Try performing push-ups in between bouts of 2 minutes of high intensity jump rope for a great cardio workout. http://AskTheTrainer.com/best-cardio-workout.html
