I am hoping to reach or exceed these times by the end of 2015. Has anybody got any advice? Maybe a few good sets/sessions?
Thanks,

It's complicated metabolic stuff which I only have a vague understanding of, but the principal physiological goal of USRPT is to convert, through a pariticular training process, Type IIb muscle fibers, which are fast twitch anaerobic, into Type IIa, which are fast twitch fibers that run on oxygen. This stimulation occurs in the threshold zone between aerobic and anaerobic. USRPT sets are designed to keep you in that threshold zone as long as possible. Its like a hybrid metabolism; anaerobic muscle fibers that actually run on oxygen.
