We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
A Compound Set refers to two resistance exercises using overlapping muscle groups. For example, bench press sets alternating with dumbell flies - that is mostly two chest exercises. Another: dumbell bench alternating with tricep push-downs. The overlap there is two tricep stresses. People do Compound Sets once in a while to kick the heck out of a certain muscle or two - and for variety to keep the body off balance a bit.
A Superset, on the other hand, refers to alternating two resistance exercises involving opposing muscle groups. That is something we commonly do in weight training. Push-pull. For example, dumbell bench alternating with pullups or pull downs. Another: Curls alternating with tricep push-downs. There is a balanced logic to this.
(Compound Exercises are resistance exercises which apply the largest number of muscle grouds possible for strength-building. The Big Lifts. These are the classic multi-muscle group exercises: Bench Press, Rows, Pull ups, Dips, Deads, Overhead Press, and Squats).
