I know that training by Heart rate is considered old school or inefficient on this forum, but i do not have a powermeter, i doubt i will have one in next 10 or so years. So, can somebody convert the terms like 20x20 or SST, FTP to % of HRmax terminology? Or point a link to thread where the training is described based on %HRMax? Advice for a good book (with winter training plans) for person who can exercise only 5-10 hours per week needed as well.
P.S. I did use search machine, but with little success
