In every fitness routine, you will hit a plateau. A plateau is a stop in progress. You may be eating right and exercising right, but you measurement of progress has stopped. This measurement may be your weight, how fast you can run or how much you can lift. You need to get past the plateau. To do this, you need to try something different. Try this workout out.
The century workout should tell you that you are about to do something 100 times. Reduce your normal lift for each muscle group to 1/3 of what you have been doing. Now, try 1 set of 100 reps. It may seem like a waste of time for about 50 reps. It will become a muscle burner after that.
Doing this shocks your muscles because you are doing something completely different. This is how you can help push your way over the plateau.
