Instead of keeping it at 150lbs for Friday (since that would be 5lbs over Wednesday's 20-repper), I think I will bump it up to 155lbs. Then on Monday, I can tack on my 10lbs like I planned and do 165lbs (body weight)!
That'd mean that for the second 1/2 of the program, I'd be starting with body weight. Not too shabby I guess. If I get to 175lbs BW by the end like I should, then a "decent" squat would be about 255-260lbs. That would be 1.5x body weight and I'd be happy with that. But to hit that from 165, I'd need to increase 90lbs, which isn't going to happen unless I tacked on 10lbs each workout. Maybe that's doable now that my back has seemed to catch up and hold the weight and my legs aren't really the limiting factor. We'll see how it goes.
8 down, 10 to go!
