I talked to some SEALs the other day about their workout regimen. And what makes them physically elite is that they PT twice a day, and they PT HARD. I have Dive PT and that is hard shit and it is also twice a day. And I looked at this workout and thought it would be a great challenge. And best of all it requires no weights but it is quite lengthy. And by the way if you don't know about the great shape that divers are in we do more PT than Army Rangers (they only PT once a day) Sorry for the bragging, I'm proud to be a diver

If this workout is done at least three times a week you will notice a huge increase in speed, agility, explosiveness, and strength. Supplimented with a lifting routine on off days you will become a hard, ripped, animal and I will garauntee you will kick anyone's ass in a pull up or push up contest. I haven't been beat yet. It works awesome.
