Four Dimensional Power Focus:
Chores. They're rarely glamorous, almost never fun, and more often than not you need a hot shower and a long nap afterwards. Sort of like this workout. If you want a 'do-it-all' session, that will maintain and improve nearly every aspect of your fitness, then you're in the right place. Each set combines a series of 40 second efforts and 20 second recoveries with a sustained effort just below Threshold. The benefits are substantial. First: with such short recoveries between hard efforts, you'll pretty much empty your anaerobic fuel tank by the end of each set. This obviously develops your AC, but as your body is forced to rely more and more on your ability to produce power aerobically as your AC empties it gives your maximal aerobic (MAP) a real shove. As your body shifts from AC to MAP and begins producing almost all power from oxygen, the workout puts you into a sustained effort just below threshold. These same sustained threshold efforts when fresh would be a piece of cake, but by starting them deep in the red you will find them to be much more difficult than you might think. These efforts will push you right to the edge, but never over, so dig in deep and get your chores done!
