Jillian Michaels says 85%. This is 220 minus your age, times .85.

Mine is 157, according to her. 220-35=185x.85=157.

To find out the exact zones for you.. you would need to get a VO2max test done -- this will tell you what your different zones are for you specifically and then you can make sure you're training in the right one..

but my zone high is about 153 i think.... but when i'm working hard in a spin class i get to 170, and it feels good, it's gotta be good doesn't it? yesterday i hit 179, i was going crazy, and i felt great afterwards. i don't want to hold back when i can go crazy and drive it through the roof.
