I found some great YouTube videos to get me moving along. I know a lot of readers out there probably do not know how do a proper push, so I hope this helps. I was doing these all wrongs before Drill Sergeant Jonesy showed me otherwise. These videos helped me improve my form.
This Urbanathlon is good for me because it forces me to work out my weak upper body. It took me a few years to master the art and science of running marathons. I know that with training and discipline, I will reach the point where I can pass a military physical fitness test. It won't happen in time for next weekend's Urbanathlon, but eventually I will get to that point. Damn those monkey bars!
