The Casanova workout is not named for the reason you may think. Its namesake was never off the job, so to speak, and similarly in this workout you never get a lot of chances to rest your muscles. Its particular combination works major and minor muscle groups and recruits a variety of supporting muscle groups and tendons for a total body workout that simply keeps on piling the pressure on. The emphasis here is on strength so you really want things to be executed with perfect form and at a moderate pace. You want to avoid turning this into an aerobic workout so breathe deep and evenly and maintain a strong, measured pace. Add EC.
Extra Credit: 1 minute rest between sets.
