This is very effective
Try this! Use this method as one mega set. Let your gym routine consist of four or five mega sets each set has compound exercises. For example, one would have a primary exercise, followed by two additional exercise, targeting the same muscle group. Try not to allow more than 90 seconds to pass in between each Mega set, but when exercising a Mega set, do not allow any breaks between the exercises. Again no breaks between the three compound exercises.
