Ramp-ups

Twenty minutes today on the elliptical. That's it. But a mad 20 at that.

Ramp-ups start at a level of effort of 5 (where 10 is as hard as you can go) for 5 minutes, then a minute at a 6 effort level, then a minute at 7, then at 8, and a minute at 9, then back to 5, up to 7, 8 9, and 10, and back to 5 to cool down.

They're devilishly evil. In theory it sounds pretty simple, but by the time you reach 10 your eyeballs begin to bulge. And the fat guy next to you wonders what your problem is.
