Long distance running is the worst exercise that anyone can do. It shrinks the heart and lungs, and does nothing to lower bodyfat or build muscle tissue. Walkers have my respect. It is a good exercise for your entire body. BTW, here's what I did on my last birthday:
http://www.youtube.com/watch?v=zGG8GKiBbG4&fmt=18 Excuse me? Where did you get this information from? If it shrinks the heart and lungs, I guess I should be dead now (I'm 61) but I do agree that it definitely doesn't build muscle tissue due to the buildup of cortisol. But it does lower bodyfat. I know this both from my personal experience and the anecdotal experiences of others.
Why do walkers have your respect but runners don't? Incidentally I still lift wts. like you do. Why do you do deadlifts with dumbbells? I'm a big believer in doing "deads" myself. I routinely do 3 X 10 w/225 lbs. and sometimes go as heavy as 405. By the way, do you do squats? I see you do lunges but I would suggest you use lighter wts. and utilize better form. That also goes for your rows. Don't jerk the wt. but rather use a slower more controlled movement.
Do you do any separate cardio at all or do you get it from your wt. training? You need to work your legs more from what I've seen in the video. Heavy squats should do the trick and if you really want to get a good combined endurance/strength workout, try 20-rep sets of squats.
Lastly, when you do your "push presses" , drive with your legs more and lock the bar above your head. Have you thought of using a lifting belt?
I hope you take this criticisms in a positive way since we are brothers in Christ. I've done both - bodybuilding ( see my pic in an above post and here)

and have done 30+ years of competitive long distance running. You can ask "pkrause" who has seen me run in the Boston Marathon and other races in New England.At one time (when I was 59) I was the global leader in my age group on the Nikeplus web site and at 60 did the GoreTex TransRockies Run, running 110 miles in 6 days at high altitude (9,000ft. - 14,000ft.)
Stay strong, Mark. Your body is the temple of the Holy Spirit.
