Iron Man Workout

I found this workout from Craig Ballantyne off of Men's Health (http://transform07trainer.menshealth.com/) and it is quite intense. It's "easy" because it is all bodyweight-your essentially using your body as the weight that is being pulled, pushed, jumped, lifted, etc., BUT it is not easy by no means because there are no breaks and pushes you to the limit.

Do this circuit and repeat as much as you can until your are ready to drop:
10 exercises 125 reps
5 pullups
10 Jumps
15 Close-Grip Push-Ups
10 Lunges (Each Leg)
5 Chinups
10 Mountain Climbers (Each Leg)
10 Inverted Rows
10 Single-Leg Deadlift (Each Leg)
25 Bike Crunches
15 Step-ups (Each Leg)
15 Decline Pushups

Try to not take any breaks when going through the circuit and then once you are done you keep going to be a true Iron Man. Another great thing about this workout is that it can be down on a playground that has the right equipment, which makes working out an event you can enjoy in the nice summer sun!
