Just reviving this one out of curiosity as I am doing a lot of learning in this department lately.
Is the traditional base program on TR scheduled in such a way that promotes long slow distance route to improving Aet and LT2? Whereas, the SSB program is more geared towards time crunched individuals, and as such, the programs are shorter in duration but more intense? For my own clarity here, is this is why the SSB program is touted as the major go to program to build your base on TR? And seems to work for quite a lot of TR users?
