Andy's video is pretty good. Will you lose absolute strength? Yes, of course. But what he's recommending will do a lot to keep form losing too much mass and keeping work capacity high. Having just done a 3-week layoff prior to this all exploding, and not having done much at all during that period, I can say that work capacity was the biggest loss. First day back I worked up to conservatively heavy singles, and while I didn't push to hit prior PRs I was close on most lifts (actually my press single was the same as my previous PR for singles across). But doing in subsequent days, doing multiple sets even at lower weights was pretty tough. Anyway. Point being, it's a decent workout and will provide decent conditioning if nothing else.
