Here's my spreedsheet up till now. Ignoring the few blips in the weight I lifted...I've made a huge effort to get those numbers up. It will make or break your gains IMO. You
have to up the cores.
I'm approaching my maxes right now, so I up the weight by 5lbs and do
as many of the 5 sets as I can with that weight and then if I can't continue with that weight I go back and lift last weeks weight for the rest of the sets. I only record the new weight lifted if I can make the 5x5, otherwise I put last weeks weight so I don't forget that I didn't make the 5x5 last workout.
Use your judgement when you increase the weight, it doesn't have to be 5-10lbs, it can be anything as long as it's an increase.
