question about the workout, should I stop upping the weight if i can't get all 10 reps on my second set or keep going up as long as my first 10 are good?
Only the first set of 10 reps matters. That first set HAS to be made. The second set is mainly for added volume. You could potentially cluster it if you had to. That means that you get, say, 7 reps on your second set. Rerack the weight and take a quick breather. 20 seconds or so later you nail the rest. This is also known as a rest/pause.
Make sure that you try your best to get that second set without form breaking down. Don't cluster the second set unless you have to. Another option is to rest a little longer between sets. If the first set was super hard, but you nailed all 10 reps, take an extra minute to relax..Go walk over to the water fountain and wet your mouth. Just don't lolly-gag for 5 minutes or something.
Also, it's not unheard of for most people to drop that second set of 10 the closer they move to their true 10 RM. Progression could look like this:
10 RM (two week mesocycle)
Day 1- 2 x 10 squats
Day 2- 2 x 10 squats
Day 3- 2 x 10 squats
Day 4- 1 x 10 squats
Day 5- 1 x 10 squats
Day 6- 1 x 10 squats (10 RM day)
Same goes for the 5 RM. Most people can start off with 3 x 5 for almost everything, but as the cycle progresses, and the weight becomes very heavy for you as you come closer and closer to your 5 RM, you could drop to 2 x 5 for everything and so on....
