One of the most effective workouts I do on a regular basis is the Coggan Power Interval.  This has proven to drastically improve my power output, more so than any other single workout I have ever done.  I did a LOT of searching on the internet before I found out what seems to be the preferred method for this effort.

If you don't know your Power Threshold, then you need to determine that first and foremost.
