Did You Know About Muscle Confusion?

Did you know about muscle confusion?

I have used the same three workouts for several years now. I get bored with it and don't really see any results in strength or toning. My husband does a different workout nearly every week. He calls this muscle confusion and says it is good both for the body and mind. So yesterday I worked out with him. I did his strength training routine and then ran one mile on the treadmill, spent twenty minutes on the elliptical machine, and ran one more mile on the treadmill. I am not sore or anything today, but it was different and took away the boredom.
