Q&A #13 - Bike power indoors vs. outdoors, and are recovery weeks necessary for low-volume athletes
Q&A #13 - Bike power indoors vs. outdoors, and are recovery weeks necessary for low-volume athletes If the difference between your FTP indoors and outdoors can be 20-30 watts, do you need to test your FTP separately in these different conditions? What are the factors that impact how big (or small) of a difference you will have? If you're only training 7-8 hours per week, do you really need a recovery week every 3 or 4 weeks?

Q&A #12 - Heart rate or power zones, and incorporating additional races into a training plan
Q&A #12 - Heart rate or power zones, and incorporating additional races into a training plan Why it makes sense to train according to heart rate rather than pace or power in your aerobic endurance training, as long as you are aware of some caveats.

Q&A #11 - Should you use different heart rate zones for swimming, cycling and running?
Q&A #11 - Should you use different heart rate zones for swimming, cycling and running? According to Dr. Phil Maffletone, the aerobic threshold heart rate is the same in all aerobic sports (like swimming, cycling, and running). Is this true? How the type of athlete you are and your ability and experience in different sports impacts whether your heart rate zones will be similar or not between different sports. Practical examples from lab tests and research studies showing massive discrepancies in threshold heart rate between sports (we're talking 10-20 bpm differences) The problems with the MAF-formula or 180-formula for aerobic threshold heart rate.
