I have problems with this guy. First he recommends two exersizes I wouldn't: situps and sidebends. Situps have been proven lousy for the abs and are hard on the spine, and sidebends would only be needed for certain type waistlines. OTOH, he then advocates weighted situps with a db on the neck and flexing the biceps whilst holding the db. I certainly wouldn't benefit from them. Then he goes on to say that squatting is a great bicep exersize...WHAT? Oh, I'm supposed to be flexing my biceps here too...even though isometric contractions have been repeatedly proven insufficient...
His program seems to be a mixture of sound advice, conjecture, and brologic. I just skimmed the rest, losing interest. Sorry for the bad review; it's just what I see here.
Oh, and nothing wrong with 2x/wk workouts, as long as you make them count - even with HST. We have threads on that.
