For the past few years I've been in maintenance mode, but I've decided I want to get back into serious training, and have been giving Foundation a shot. Right now I'm figuring out where in the program I am by testing out the masterys of the progressions, but am not positive on the rest times. It says to rest just long enough to do the integrated mobility...so for a 5x60s mastery, am I really supposed to not even have a minute or two of rest in between sets, and just bust sets out back to back? Ouch.
