The dope on CrossFit, described in this L.A Times piece as "a free, fast-growing, largely underground workout plan that some say is rewriting the rules of fitness," is that it really can help you develop aerobic fitness and strength training at the same (very short) time. How does it do that? Geezer can answer in one word: intensity. Geezer is convinced that if you worked as hard at anything—say washing the car– as people do at CrossFit training, you’d build aerobic fitness and strength and several other things to boot.
Writing for the LA Times, Roy M. Wallack tells us that CrossFit takes basic, functional-fitness exercises  squats, push-ups,
pull-ups, dips, dead-lifts, medicine ball throws and more  emphasizes
full range of motion and adds short bursts of cardio. Then it
throws them into a blender and flips the switch to "purée." At the moment, says Wallack, there are 84 official trainers who teach
CrossFit in major cities around the country. Still interested? Most of them can be found here.
