So this routine sounds like it may be just about perfect. I can easily do the pushup workout on days I'm scheduled to run as well as the days I want to recover or do some cross training.
It also has a Smart Phone and iPad apps, which should make it very convenient to record and track my workouts.
So here it is..."I'm Doing the Hundred Push Ups". Now it's reality and I'll be sure to provide updates about my thoughts on the plan and my progress.
