When should I increase my loads? Confused!

[Akagorr68]

When should I increase my load? I have read on the internet alot of advice with no real logical consensus.

Situation: Let's say I'm doing four sets of squats at 10-12 reps each. Let's say the 12th rep on the first set is a struggle (pretty hard), but might even get 13, maybe not14 (not likely).

So which one of these are the answer?

1. Stay at 12 reps until it becomes easy, that I could do 14-15 reps.
2. As soon as you can do 12 reps, it's time to increase.

If you think number two, do you treat your sets differently? Say I squat 205 12 times the first set, but only 205 10 reps next set. Should I increase set 1 and and wait for set 2 to catch up?

Bonus question - Do you believe in straight sets? Like 205 for four sets? Sometimes I will drop the load just so i can stay in the rep range since i am stronger on the first set.

If your goal is four sets of 12 reps, then the first set of 12 should be EASY to get. You should only struggle to get your full amount of reps on THE LAST set. When you can successfully get all your reps on the last set, then increase the weight.

The answer depends on total training volume, intensity, and other factors. What is your training goal?
