Last year I started the 100 Pushups program and was impressed at how easily I was progressing with just a little effort a few days a week. I never made it to 100 at one go, unfortunately, but mostly because it became, well, boring. That said, I still do pushups and the website was a starting point. Last month I found and became interested in the Couch to 5K program and have been waiting for spring to start running, so this app would be great. My shoes are ready...
