crossfit
been messing around a little with some of the <a href=”http://www.crossfit.com”>crossfit</a> exercises. basically they’re timed workouts composed of a very large range of crossfit exercises (examples are posted on the site). apparently these workouts are kind of limitlessly hard in the sense that you can always improve in some aspect, since most of them are timed.
also, the workouts are weirdly named after women, not sure why. I tried “cyndi” which is 5 pullups, 10 pushups and 15 bodyweight squats, do as many sets as you can for 20 minutes. I only managed 13 sets and was very, very tired at the end of the workout. bodyweight squats are deceptively difficult, I was pretty sore the next day.
they have ramp up classes in nyc that teach you all the exercises and help you get started (it incorporates things like gymnastic rings and kettlebells), so that might be interesting to take at some point post half marathon training.
