Have been having success with this, (rotating) but want to make sure it is OK to proceed this way. Is it better to do all three sets together with breaks between, or is it OK to do one set of X than do another X in rotation? I normally do 1 set, working one muscle group, than do another group till end of the rotation, than I go back and start over for a total of three sets. With each set, I increase the reps by a few reps (10, 12, 15) What's the best way?
