Push-ups on Exercise Ball

A standard push-up is already a challenging exercise that includes the use of many different muscle groups, including the abdominal and lower-back muscles that collectively make up your "core". By doing this movement on an exercise ball, not only do you radically increase the recruitment of those core stabilization muscles, but you change the way the upper body muscles are recruited as well. By modifying the way a muscle is used, you get the double benefit of strengthening it from a different "angle" while at the same time increasing your level of neuromuscular coordination - the mind-muscle link.
