You can do a self test pretty easy on the bike, I use a ramp test where the resistence is increased every minute until failure (This is maybe a Conconi test, but I'm not sure of the spelling) Here is what the numbers looked like with a 10 watt per minute increase, note where there is a sudden jump, that's where the AT is, you can then build out the rest of the zones based on that, since my trainer has watts, I base my workouts on the numbers right around the jump and try to make the jump happen at a higher hr--see what I mean below:<br><br>
