I've done a little research on an upper body workout for endurance training and strength building that also works in discipline. It's the 200 push-ups a day challenge. Has anyone done it? What were your results? Currently I'm on 60/200. I'll start back shortly. I want to use this post as my training log. Tomorrow I'm gonna work in ab work and body weight legs. Legs will most likely be squats. I want something simple that will help me stay in shape while working other things. I believe this will be the best for my busy schedule too.
