Karl, I subscribe to using MAF in general only as a very rough guide. Most important is the feedback I see working with an individual over time.Agree with both these points.
I definitely sweat a bit more on the rower as there is no cooling breeze (Concept C2 fans are useless for cooling).
Would you subscribe to the idea of varying MAF rate according to exercise? Or are all these forms of locomotion similar enough to stick with the 180-Age formula?
In general, I'd say yes--you should drop target HR in an activity that causes, relatively, unusual spiking of your HR.
