@alexander5106954665 You aim to progress on all sets, but train hard on all of them, so don't worry if you don't progress on all.
Example, you got 10kgx12,10,9 this week. Next time at the same RIR, or lower/hardrr, however you train, you're able to get 15,11,8. You progressed your main set and trained hard. That's important. Don't do something like 13,11,10, just methodically adding 1 rep per set when you could do more on set 1.
But in most cases, even when training hard, you should be able to progress on all sets. If you don't, don't worry. It'll happen eventually.
