Muscle Confusion – the Key to Strength and Tone?

About 3 weeks ago, I met my workout partner at the gym on a Saturday morning and we ran through a new workout sequence that Michael called a “super set.”   This involved 50 repetitions of a variety of machine equipment exercises set at a medium weight.   We did leg presses, seated arm presses, seated tricep push downs, hamstring extensions and seated shoulder presses.

That afternoon, I was so exhausted, that I took a 3 hour nap.

Over the past 3 weeks, we have added this “super set” to our weekly routine – performing it twice a week and even adding additional exercises.  This morning (Saturday) we did a super set that included more exercises at higher weights than the one we did three weeks ago.

I have a normal post-workout burn but I am not fatigued like I was after that first set and I feel no worse after doing these super sets than I do with any other exercise routine.

I suspect that muscle confusion and muscle adaptation offers an explanation.  I do find it interesting that the fatigue associated with muscle confusion happened only after that first set.

I am thinking that I need to come up with different routines to re-create that muscle confusion, both for weight loss and for increased strength.
