STS features three mesocycles, each lasting four weeks. Each mesocycle is designed to stimulate your muscles and body in a different way.
The STS workout routine is designed to be simple and easy to use. Every STS DVD is numbered so that you can easily identify which workout DVD you will need for that day's workout.
Each week combines workout exercises you have done in the previous weeks with totally fresh exercises that you haven't done before. This way you always have some exercises that you are familiar and more comfortable with and new exercises that will keep your body's muscles always guessing and challenged in new ways.
You will notice that every workout in the STS strength training workout routines has an information bar located at the bottom of your screen that will appear at the beginning of every break and will then disappear once the break is over. The information bar will always display how much time is left before the next exercise begins and will tell what the next exercise is as well as what equipment you will need. Other information like percentage of one rep max, reps and targeted muscle groups will also be displayed.
