12 week FTP builder - FTP testing

Hello everyone,

I’ve got a quick question about the 12 week ftp builder program.

I’ve done an FTP test before starting this program. How often should I redo the FTP test? Or is it best to only do it on the beginning and at the end of the program?

Excuse me for asking something stupid. I’m kinda new to actual cycling training.

Cheers and ride on!
