Here’s something for your pecs: hundredpushups.com. This site offers a six-week program that claims (plausibly, I’d say) to be able to get you from your current fitness level to the ability to do 100 pushups in six weeks. I started a little over a week ago, and the workouts seem well-calibrated, because I sometimes struggle to get to the end, but I can make it. At the beginning, I was able to do 16 pushups at a go. There’s another test at the end of this week, and I’ll be interested to see how much progress I’ve made.
Anyway, if you’re looking for something to shake up your exercise routine, give it a shot.
