This is the next workout phase from the book "Complete Guide to Navy SEAL Fitness" by Stew Smith, former US Navy SEAL. It is very intense, especially as the weeks go by, but it is intended to follow the withfit program SEAL Beginner to Intermediate, posted by the same creator. At the end of (show more) the first program, you should have built up enough strength and endurance to begin this program, and your fitness levels should keep rising as you progress, allowing you to keep up with the work prescribed. If not, feel free to repeat a troublesome day or week, or just go on to the next one. It's more important that you give 100 percent effort, because if you do, your body will respond favorably.

Before each workout, warm up with 3-5 sets of 10 jumping jacks and 10 pushups, just to get the blood flowing. Make sure you stretch your whole body before and after (show more) each workout. Make sure you are giving yourself adequate periods of rest between sets. If rest periods are not specifically given in the workout or exercise instructions, rest only until able to go on to the next set or exercise.

Some days have multiple workouts given. This was only done due to the limit on numbers of exercises per workout as imposed by the withfit programming. In reality, on each day, there is one workout. You will do all the workouts listed, in order. Again, this is very intense. It is meant to prepare potential recruits for the harshness of SEAL training. Look at it as if you were in the military, and each workout were simply the PT session for that particular day. Eventually the 12 weeks will be over, and you will be in much better shape, with a much higher fitness level. (show less)
