Not at all specific enough...
I want to know (along with 50 other people who posted the same question) clearly how to distinguish b/w HIAnaerobicIT and HIAerobicIT and at what work to rest interval protocol. Also, sample routines for each proposed span of workout time would not have been unwelcome.
The editor in me would have sent Alwyn back with a sheet of notes.
Then again, perhaps this is just article 1 in a 2 or 3 part series? I can hope.
