Would temporarily increasing the rest time between sets and then gradually decreasing it to just the length of the iM be an effective method of progressing?
For example, ABH: I can do 4x36 with good rom if I rest for a minute after each iM. But without the extra rest I'll start losing rom after set two (and set four will be abysmal).
Or perhaps I should decrease the hold time and work to a strict 4x30, and then 4x36?
Cheers!
