..better yet, don't waste your time. If you don't have a power meter, your functional threshold is probably a mystery to you anyway, so doing FT intervals as I've done here will be impossible.. (let me add that it is possible to own a power meter, not know what to do with it, never establish your FT value and hence never do workouts designed to boost it (FT) and then end up giving your power meter away or selling it because you judge it to be a useless toy..) Furthermore, if you are using a heart rate monitor for such a work out, then you're going to be way off the mark.. The three intervals pictured are all pegged at 241 watts average (5 min, 10 min and 10 min), but lo and behold- the heart rates for the three intervals average at 152, 164 and 170 respectively. If I "believed" my FT was 160 beats per minute.. interval No 1 would have been higher than my FT watts. Interval No 2 would have been lower and interval No 3 would have been lower still. So.. using a HRM I would have ended up blowing my wad on the first interval because it would have been anaerobic, and then I would have done a couple of zone 3 tempo intervals when I'm trying to be on the edge of zones 4/5... Useless. The chart speaks for itself though. Look at the slow reaction of the heart rate. It takes a full 30 seconds for the HR to reach a level which is compatible with the output. I realize that not everyone can afford to pay a coach.. but make no mistake: I sacrificed something else in order to free up the money for coaching. If there's a will, there's a way.
